It wasn’t the first time Demi Lovato had been on a movie set with the Jonas Brothers, but she did reveal that shooting the sequel “Camp Rock: The Final Jam” afforded her the chance to make some great new memories with her pop-star besties. In fact, she had such an amazing time shooting with the group that she couldn’t help but rave about it days after wrapping.

“It was so much fun doing ‘Camp Rock 2,’ ” she told MTV News on the set of her new music video for “Remember December.” “I had some of the best memories in the world there. It was a blast.”

And Lovato doesn’t just credit Nick, Joe and Kevin for the great time she had working on the film, she also thanks the new faces that joined the “Camp Rock” stars for the film’s sequel. “It was incredible being back with the cast from the first one, and we had new castmembers. We were so excited to be able to shoot again and make new friendships. I loved it.”

One of Lovato’s favorite on-set memories happened the day she and the JoBros shot the parody rap video for their song “Bounce.” “I think a lot of you guys out there heard about the music video out there, ‘Bounce.’ … We ended up shooting the music video one day before we all went to work. It was just so much fun. It was incredible,” she said.
