Demi Lovato wears rhinestone-covered jeans to perform with the Jonas Brothers

She’s really good!

On Sunday, Demi Lovato joined the Jonas Brothers on stage in New Jersey for the opening night of the JONAS20 tour, dazzling in statement-making rhinestone-covered jeans.

For the “Camp Rock” reunion, Lovato, 32, slipped into a pair of slouchy crystal-adorned Acne Studios jeans ($1,400).

She skipped a shirt, opting instead for a gray bikini that showed off her abs for the balmy outdoor concert.

The “Cool for the Summer” singer’s ex Joe Jonas, 35, whom she briefly dated in 2010, rocked a brown sleeveless vest and coordinating straight-leg trousers for their medley of duets.

Much to the delight of millennial fans, the duo performed hits from their 2008 Disney Channel movie and its 2010 sequel, including “Gotta Find You,” “This Is Me” and “Wouldn’t Change a Thing.”

“Joe got the job, and then somehow our dad figured it out to get me and Kevin to be involved in the movie, too,” Nick Jonas told the crowd before they brought Demi out. “I think it’s time that we all walk down this memory lane to celebrate a little movie called ‘Camp Rock.’”

Meanwhile, Joe stated that it’s been “almost 10 years” since he and Lovato performed together, though she added that it “might have been longer.”

Lovato shared a humorous Instagram Reel of the two mouthing to a viral red carpet meme of former Disney Channel star Debby Ryan. “for the history books @joejonas,” she captioned the post.

“My one thing is I went into the Disney Channel building, and I sat down with the president of Disney Channel, and I said ‘I wanna make history.’ And that’s what this is,” they quoted her iconic line.

“camp rock 3 is totally happening,” one person commented. “seeing this video is one of the greatest moments of my life,” a second added.

“Gonna need years to recover,” another said.

The reunion we all needed.
