Confession Time: Joe Jonas Comes Clean About the Elevator Prank with Demi Lovato

Gotcha! Remember when Joe Jonas got stuck in an elevator with his ex Demi Lovato? Yeah, that didn't actually happen.

"It was a lot less dramatic. It was a total prank and we fooled everyone," he told PEOPLE. "I made the video saying we got stuck in the elevator, but we really weren't. But I guess it's bad karma to say that because I don't want to get stuck in the elevator anytime soon."

On Thursday, Jonas, 27, shared a Snapchat video of he and Lovato, 24, saying they were stuck in the metal box for "four hours" in Los Angeles. His DNCE bandmates JinJoo Lee and Cole Whittle were also seen in the background.

"[Demi and I] were talking yesterday and I said, 'I think we fooled everyone because it's on every press site,' but we really weren't stuck in the elevator."

Jonas was far from an elevator on Saturday. Instead he was in a place he feels very at home – on stage at the iHeartRadio Music Festival with DNCE.

But he's not an all-out fibber when it comes to his ups and downs.

"I have been stuck in an elevator before and it was terrifying," he said.
