Demi Lovato celebrated her 30th birthday with her friends and her musician boyfriend Jute$ on Thursday.

The singer uploaded a series of snaps on her Instagram Story as she was surrounded by white balloons with the words "Demi 30" written in the background. In the photos, Lovato made cute poses with friends in a sexy red cocktail dress under a black fishnet outfit. She posed with her friends Matthew Scott Montgomery, Paris Hilton, Kristen Stewart, Ashley Benson, Kaia Gerber and "Eat Me" collaborator Royal & the Serpent.

Benson uploaded photos from the party on her Instagram page and wrote, "Best time celebrating my little love."

A fan also tweeted a clip showing the "I Met Him Last Night" singer excitedly blowing her birthday cake as her guests sang "Happy birthday."

"They might not be as popular as back then but looking at their life and happiness right now is so fulfilling to see as a fan 🥹 this one right here gives me a smile!! protect demi Lovato at all costs," the fan tweeted.

Paris Hilton also tweeted photos showing her posing with the birthday girl in a black two-piece outfit.

"Happy Birthday @Ddlovato Had so much fun celebrating with you! Your smile lights up the room and I love being around your beautiful energy! Love you forever," Hilton said.

In her Instagram Story, Lovato wrote, "my baby" as she posed with Jute$. In another photo with the Canadian musician taken from a photo booth, she wrote, "My best friend."

Lovato recently made her relationship with Jute$ official when she posted a sweet photo of them ahead of her birthday.

A week earlier, a source told E! News that Lovato and her beau have been secretly dating for months after working together on her new album, "Holy Fvck." Punk/rock artist Jute$, 23, co-wrote Lovato's new tracks "Substance," "Happy Ending" and "City of Angels."

"Demi and Jutes met while working on music together. Things are going really well and they have a lot in common. They bond over music," the source revealed. The insider also shared that Jute$ has "restored her faith" in love after Lovato broke off her engagement with Max Ehrich in September 2020.
