Marcos POV:
I saw a girl outside our door she looked very familiar... "Star why the hell are you blasting her?"
"HIDE YOUR DRAGON EGG SOME WHERE ELSE!!"
"Star she isn't a post man /woman ." I chuckled whilst saying that .. Some people with cameras were surrounding her warning this will be an "oc" if you don't like them too bad she was banging on our door to let her in .. So I did , she rushed in panting really hard .. "Thank you sooo much , im sorry I don't really know you its just I need help at the moment."
I just realized who she was I am legit gonna add Ariana grande in this .. Just imagine her in the art style.
"Oh my god your Ariana grande , what the hell are you doing in echo creek ?!!" Star seemed to be standing there confused and displeased also imagine Ariana is17 but still how she looks today

Stars POV:
I saw a girl with really long brown hair and she was quite skinny and very pretty , she was banging at the door , Marco let her in and suddenly realized who she was her name was 'Ariana grande ' or something she sounded Latino of some sort but didn't look it key point I know Ariana Is Italian
Marco seemed to be fangirling over her if she was some sort of celebrity (I don't know what they are I think they are people who get a lot of money ) we have people like that in mewni, I guess I'm a celebrity then I don't know. " Hi Ariana , I'm sorry I was narwhale blasting you earlier , I feel stupid now ."
" oh its okay , I'm just glad your boyfriend let me in before the paparazzi suffocated me ." when she said that she closed the blinds and blew a kiss to them . she seemed sweet but I feel like she's a threat to me and marcos chances .. But marco would never choose a complete ... Stunning ... Famous ... Kind stranger over me , would he ??

Authors note:
Okay I hate oc's /crossovers and characters from the real world in fan fics but , I had a weird dream about ariana joining their school and I was like , fuck it why not use my dream in some writing so this is gonna be a thing but I won't say which one marcos gonna choose tho .. I will update another chapter now also when my iPads charged ( art is my speciality ) I will create Ariana in darons art style .. When I update the next chapter please vote Ariana or star , I think everyone will vote star , but be pacient and read the next chapter and you might change your mind ~renee ❤
