'DWTS': Demi Lovato Hits the Ballroom -- and So Does Chris Soules?!

The stars aren't just competing on Monday's episode -- they're sitting in the audience. 

The stars aren't just competing on Monday's episode of Dancing With the Stars -- they're sitting in the audience!

DWTS alum Rumer Willis and Queer Eye star Bobby Berk cheered this season's contestants on from the ballroom, but it was Demi Lovato and Chris Soules who had Twitter freaking out. Soules' presence at the taping marked one of his first public appearances since his involvement in a fatal car crash in 2017. The former Bachelor served a two-year probation sentence for leaving the scene of a personal injury accident. 

Soules, who competed on season 20 of DWTS in 2015, was likely at the taping to cheer on his former partner, Witney Carson -- but fans couldn't get over seeing him out and about. 

Lovato, meanwhile, is good friends with Bachelorette Hannah Brown (and currently dating her ex, Mike Johnson). She was seated next to Brown's other friend -- and fellow Bachelor alum -- Demi Burnett. 

Not only were fans shook over the star-studded ballroom audience, but the pros and celeb contestants were, too! A few of the dance couples raved about who they were most starstruck by while chatting with ET following the show.

"I was literally about to go on stage and Demi Lovato was like, 'I love you, I love you,'" Karamo Brown shared. "Demi, I just want you to know I was going fast but I love you too. You are the world to me, everything that you do and advocate for your music, your beauty, your style. I adore you, please just know that!"

"Legit, I almost freaked out," he continued. "And you know what? I'm not going to blame my low scores on Demi Lovato, because Demi Lovato only deserves people to say how much we love her and what a 10 she is, so I will tell you this... I'm just going to slide into the DMs tonight so that Demi Lovato and I can become best friends. So that way, next week, I do her proud. That's it."

Carson, meanwhile, was stoked to be reunited with Soules. "I just gave him a huge hug!" she exclaimed. "I haven't seen him literally in years, so the fact that he was here tonight was a huge surprise. I had no idea he was going to be there."

Emma Slater also had a fangirl moment after seeing Zooey Deschanel in the crowd. The actress stepped out with her new beau, Jonathan Scott, marking one of their first public appearances together.

"Zoey Deschanel was there and I about freaked out. I had to go over there with big heart-shaped eyes, like, 'Excuse me, I love you," said Emma, who previously competed with Jonathan's brother, Drew Scott. "She's got one of the best quotes about having a tender heart and don't let anybody tell you that you should be shushed or you should cover up and try to hide it and honestly it affected me. It changed my life, so meeting her was an honor."
