Joe Jonas may have revealed a closely guarded Disney secret.

The DNCE frontman was asked to read his latest entry in the Notes app on his phone out loud during his appearance on “Hot Ones Versus,” and his honest answer shocked his siblings, Nick and Kevin Jonas.

“Read ‘Camp Rock 3,’” he read out loud, seemingly confirming a third movie in the franchise is in the works.

Nick put his drink down and looked up in surprise as the crew laughed.

Kevin nervously chuckled and said, “Ok, that’s a pretty good one.”

Joe seemed unfazed at the potential reveal, and continued looking at his phone.

“It’s the truth, it’s literally right here,” he said as the crew continued to laugh.

“Sorry, Disney,” he added.

“Camp Rock,” starring the Jonas Brothers and Demi Lovato, debuted on the Disney Channel in 2008. The music television film centered around Lovato’s character, Mitchie Torres, visiting Camp Rock, a summer music camp. Torres ends up inspiring Joe’s character, Shane Gray, a troubled pop star.

The success of the original film spawned a sequel, 2010’s “Camp Rock 2: The Final Jam.” The Jonas Brothers and Lovato returned for the sequel, which was about Camp Rock competing against another musical camp, Camp Star. The sequel also saw Mitchie and Shane developing a romance.

The Jonas Brothers had a surprise reunion with Lovato at their concert in New Jersey on Sunday, adding fuel to the fire that a “Camp Rock 3” is coming. They sang “Camp Rock” hits like “Gotta Find You” and “Wouldn’t Change a Thing” for the Jonas Brothers’ 20th anniversary tour at the MetLife Stadium in East Rutherford.

After singing “This Is Me,” Joe told the screaming crowd that he and Lovato hadn’t performed the track for “almost 10 years.”

Joe, 35, and Lovato, 32, dated in 2010 for less than a year.

Clearly, the pair is still on great terms and Lovato’s husband, Jordan “Jutes” Lutes, showed his support for his wife’s surprise performance alongside her ex.

“Couldn’t be more proud. I love you sooo much baby @ddlovato,” the musician wrote in an Instagram Story of Lovato walking on stage.
