Dirty (and delicious) 30.
Demi Lovato rang in her 30th birthday alongside her best friends, including Paris Hilton, and was surprised with an epic four-tiered birthday cake at the party.
As seen in several Instagram Stories posted Aug. 23, Demi was presented with a custom designed Celebration Cake by SusieCakes—vanilla with colorful sugar confetti—with inspo from the artist's new album, Holy Fvck, including swirls of black, red and silver with "Happy Dirty 30 Demi" written on it.
Kristen Stewart and Ashley Benson and Maika Monroe joined in on the fun and posed for silly pics, which hairstylist CJ Romero shared on Aug. 24.
Demi and Paris also snapped a selfie during the bash, which the pop star—who performed at the Paris In Love star's 2021 wedding to Carter Reum—shared on her Instagram Stories.
Earlier this week, on Demi's actual birthday, Paris posted a series of photos of the pals, calling the Disney alum a "true and loyal friend."
"Sending you so much love on your special day," she wrote on Instagram on Aug. 21. "You are real, you are kind, genuine, strong, and beautiful inside and out. I've known you since you were 15 and have now seen you grow in so many ways. You have been through so much and you are so incredibly strong and resilient."
She continued, "I am so proud of you and everything you do and stand for. You are such an inspiration to myself and so many others... Love you for life fam."
That same day, Demi marked her milestone by going Instagram official with her new boyfriend her new boyfriend Jute$. Taking to her Instagram Stories, the "Sober" singer shared a shot of herself and the Canadian musician posing for a selfie in a bathroom mirror, along with the cheeky caption, "Bday bitch with her love."
