A continuation of the last two that was requested by 

Thank you so much, this series of one-shots are so much fun to write. Hope this is okay.

----------------------------------

It's been about a year sense I moved in with Steven. Things have been great, excluding the fact my father is always snappy with Steven now, but can you blame him? 

It's not like his best friend is dating his daughter. I chuckled at the thought with an eye roll.

Currently, I was driving a cheap rental car from the airport to a concert hall.

I flew out this morning to catch one of the guys shows in Detroit. It was gonna be a surprise to everyone except for my dad, but he went ahead and told everyone.

Reaching the venue, I made my way to the backdoor to get in, where a guard waited in post.

"No ones aloud in," the security man informed me with a quick look. As if he expected me to just walk off with that small sentence.

"The bands expecting me," I replied, attempting to make my way around him.

"That's what they all say," he huffed, slamming his clip board against the door.

I swear. I glared at him.

"Just let me in," I pleaded.

The guard turned completely towards me, pulling his dark glasses from his face.

"Listen girl," he growled, obviously annoyed, "unless you want me to call for back up to throw you out, I suggest you leave. Cause the only people getting in are the names the band gave us on this list. And guess what you're not on?"

How do you know I'm not on the list? I thought, asshole.

"Uh-huh," I raised my eyebrows. "And tell me, mister, how do you know I'm not on your list?"

"Little girl, there's only one name on the list, and I can assure you it's not you," his gaze traveled from the clip to me.

Okay, I'm done with the attitude.

"Well you listen here mister! I can have you fired in three minutes flat for being an asshole. So why dont'cha look at your little clipboard there," I shoved my finger at it, "and tell me if that one name on it happens to be y/n Perry."

The guard looked furious at my threat until he finally read the the paper. His eyes widened when he glanced back up at me.

"Y-you're really Joe Perry's daughter?" He stuttered.

"Yep," I popped the P. "And I'm Steven Tyler's girlfriend, so unless you want two very popular musicians to fire you, I'd move out of my way."

"S-sorry, miss," he stepped aside opening the door for me.

"Thank you," I smirked.

Finally, I breathed at seeing the halls inside. Now where in the world am I suppose to go?

I started wondering around the building, not having any clue of where it was I actually needed to be.

I started opening random doors, in hope to find someone to point me in the bands direction.

Five minutes must of gone by before I gave up. Opening one last door in a final effort, I was greeted by the sight of an empty room with instruments strewn across it.

Sighing, I shut the door behind me. Might as well find something to do.

In one of the corners, a piano caught my attention. A faint smile formed upon my face as I made my way over to it.

Sitting down on the stool, I started playing it. A haunting tune drifting from the instrument as my fingers danced across the keys.

Without realizing it, familiar notes started to form from my playing.

Almost immediately, I started to sing along with the music one of my favorite Aerosmith songs.

"Every time when I look in the mirror

All these lines on my face getting clearer"

I continued the evocative ballad, my voice matching the pianos pitch almost perfectly.

A warm feeling overtook me as I approached the climax of the song, my voice wavering slightly as the lyrics took a higher sound.

"Dream until your dreams come true

Dream on
Dream on"

I prepared my self for the high note that was slowly approaching.

"Dream on
  Dream on"

I took a breath as I just about screeched the next part.

"Dream on
  Dream on"

Smiling to myself in achievement, I brought the song to a steady end.

Silence filled the air once again as I pulled my hands away from the keys, leaning back with a prideful sigh at my solitary performance.

My heart just about stopped when I heard clapping coming from the doorway behind me.

Oh, I'm begging you God, I silently pleaded with my eye clamped shut, please do not let that be someone I know.

The applauding stopped as footsteps approached me.

"You know, I wrote that song when I was seventeen?" Steven's rough voice filled my ears as a pair of arms encircled my waist.

Out of everyone, it had to be him to of heard me. My cheeks flushed red from embarrassment.

"Your voice is beautiful," he purred into my ear, placing kisses on my hair, trailing down to my neck. "I didn't know you could sing."

I shook my head, refusing to look at him.

"What's wrong, baby?" I could hear the feigned innocence in his voice, "did I embarrass ya?"

Nodding, I hid my face in his arm, still not wanting to make eye contact with him.

"Cheer up, doll," he pulled me up from the stool. "I loved your performance and would love to hear it again, but it's time I go perform as well, so come and watch."

Pushing the discomfiture aside, I followed him out into the main hall. From there, he led me to the side of the stage where the rest of the band was waiting. 

Apparently the opening act just finished their set, so it's Aerosmith's time to go on.

"Y/n," Brad spotted me and waved happily.

The other three band mates turned their attention me.

"You made it," my father spoke. 

I beamed up at him while hugging him, trying to avoid knocking into his guitar.

"Yeah, just got lost," I responded, giving the rest of the band side hugs.

"Did you know y/n can sing?" Steven asked out of know where. 

Turning around, I shot him a death glare. Which he returned with a cheeky grin.

"Yeah," my father nodded, "she's been singing and playing piano since she was young. You'd know this if you weren't so out of it when she was a child."

A staff member came up, informing the band that it was time for them to go on. 

"Good luck," I called to them as they fled out onto the stage.

Steven gave me kiss before he ran out, screeching the beginning of Dude looks like a Lady.

The show went by fairly fast. I stood at the side of the stage, singing and dancing along to the songs.

An hour and half later, their performance was coming to an end. 

I watched as Steven stopped strutting around, the only sound coming from the stage was the drums and bass.

He looked over to where I stood and blew a kiss, causing the girls on that side of the stage to swoon and cheer.

"Hate to say this to y'all, but it's just about time we leave," Steven yelled into the microphone. The crowd responded with a mixture of 'aws' and clapping.

"But we have one last song to perform here," a staff member started to push the piano I was playing earlier out, "I think you know this one."

He sat down on the stool I was previously on and started the melodic intro to dream on.

Playing a little bit longer than normal, he pulled the microphone down to his mouth.

"Now, sense this has been such a rocking crowd, I have a surprise for you all," Steven began.

What in the world does he have planned now?

"Tonight, we have a very special guess attending this performance," he waved over to where I stood, just out of sight of the crowd.

Oh no, this better not be going where I think it is.

"Now I would like to invite her up onto this stage to sing this song with me," a staff member came over and started guiding me up the steps. 

My eyes widened as I started viciously shaking my head. No. No. No. No.

"Introducing, my good buddy's daughter," he bowed his arm in my father direction, "and my beautiful girlfriend, y/n Perry."

Oh, I'm gonna kill this man when this is over.

My father and Tom gave me a reassuring smile while I cautiously made my way out.

"Well come here," Steven chirped, beckoning me to his side.

"I hate you," I muttered, standing next to him.

"You'll do fine, just act like I do," he smirked.

"I'm gonna need your ego first," I retorted sarcastically, glad that there was no mics near me at the second.

The people started to cheer when I sat down next to Steven as he finally began singing.

I started to fumble with my thumbs awkwardly, wondering if he was actually going to make me sing.

Answering my unspoken question, Steven nudged my arm, standing up from the piano and pulling me up with him.

He placed the mic stand in front of me, gesturing for me to start singing where he left off.

"Half my life

Is books, written pages
Live and learn from fools and
From sages
You know it's true, oh

All these feelings come back to you" 

I gave him the microphone back, letting him continue. The audience in front of us started hollering at my sung verse. I faint grin drifted across my features at the peoples approval.

Steven quit singing as my father began his stent on the guitar. 

The chorus came up, me and Steven started alternating between each other for each dream on. 

The screeching part got closer, Steven shoved the microphone in my face. Giving me an expectant look.

My eyes widened. No way am I going to attempt to hit that note in front of this many people. I shook my head.

He gave me an encouraging nod.

My dad came over to me, leaning his back against mine as I took a deep breath in, preparing for inhuman sound to come out of my mouth.

"Dream on"

I was expecting the sound of a dying cat to come out of my mouth, but shocking myself, and most definitely other's around me. I was somehow able to hit the note perfectly, bringing in the end of the song.

Finishing it off, me and Steven sang the ending together. Letting the ballad close with the eerily beautiful instrumental outing.

I let out a long breath, relieved that it was over.

Preparing to walk back off the stage, Steven grabbed my hand before I could.

"Where do you think your going?" He smirked, obviously having something else in mind planned.

He pulled the microphone to him by a scarf that dangled from it, grinning as he prepared what was about to be said.

"Y/n m/n Perry, you are one of the most gorgeous woman I've ever seen on this planet, weird given who your father is," he stopped, giving a sly smile to my dad who scowled with an eye roll in response.

He just had to take that shot. I internally laughed. 

"But looks aside, you are by far the sweetest girl I've ever known. And baby, I love you so much. I am proud to call you my girlfriend, but it's about time I would like to call you more," the singer bent down on one knee, taking a small velvet box out from a pocket in his fringed jacket.

Oh my god, I started to feel faint, I think I'm going to pass out. 

"Y/n, would you marry me?" Steven opened the box to reveal a silver ring engraved with tiny stones, a breathtaking diamond in the middle.

I looked around, seeing my fathers and the rest of the band jaw dropped. So, he obviously didn't tell anybody he was gonna do this.

"Yes," I nodded, my eyes filling with tears and knees giving out on me as I fell into his arms.

"Yes, yes, yes," I repeated giving him a kiss.

The audience started applauding, yelling and whistling loudly.

Steven kept his arm around me until I could stand on my own again, sliding the ring on me at some point.

Glancing over at the band, I could see my father slowly taking his guitar off. His gaze fixated on Steven.

Dad came marching over, a deadly glare keeping hold on his face. 

With one swift motion, he punched the singer in the face, shoving him back, over the edge of the stage.

My dad came over to me, giving me a pat on the shoulder and kissing my forehead before stomping off the stage.

Tom came to stand next to me, peering over the edge to see security guards attempt to get Steven away from the crowd.

"Wow," Tom spoke, giving me a side glance.

I looked to the bassist, giving a thoughtful nod. "I think dad's getting better."
