The birthday girl truly committed to the '80s prom theme as she wore her hair in the signature curly look from the decade and posted a picture to her story of a myriad of disco balls hanging from the ceiling.

It looks like the Euphoria star threw quite the birthday bash if the star-studded social media posts are anything to go by. 

Behind the pink draped curtains, Sweeney's party was filled with some of Hollywood's most famous faces, from Riverdale's Camila Mendes to singer Anitta.

Mendes shared a sweet video to her Instagram story of the 26-year-old blowing out the candles on her three-tier birthday cake. 

"80s prom night was rad," she wrote on the video, alongside two pink hearts to keep to the pink hazy theme of the night.

Also in attendance was Nicola Peltz Beckham who celebrated the night with a photo of Sweeney enjoying the cake festivities. 

"Happy birthday beauty! I love you so much!!" Beckham wrote on her story. 

The A-list guests didn't stop there. The night seemed to be a mini Barbie cast reunion as both Alexandra Shapp and Ariana Greenblatt shared pics from Sweeney's b-day bash. 

"Birthday bae," Shapp posted a photo of herself, Sweeney and some other guests to her Instagram story.

She wore a sweet strapless dress that stopped just above-the-knee along with some strappy heels and her hair in a half up-do.

Greenblatt was another guest to share a wholesome video of The White Lotus star as she blew out the candles on her cake and blew a kiss to her guests. 

Brazilian singer Anitta was another big name at Sweeney's '80s-themed birthday extravaganza. 

"My first prom thanks to the bday girl @sydney_sweeney U deserve the best!!!" the singer wrote alongside a picture of herself and Sweeney to her Instagram story. 

Some guests shared the cute photobooth pics they got from the party that had "Syd's Prom" written at the bottom with a pink border and cute disco ball detail. 

Model Amelie Tremblay shared a photo of a 'Syd's Prom' banner set up at the party along with some photobooth pics she got with the birthday girl herself.
