It's not all work and no play for Kevin Jonas as he and his famous brothers shoot the sequel to Camp Rock up in Canada.

The oldest JoBro was able to slip away from the set for a bit to hit the Toronto Film Festival.

Keep reading to find out where he went and what he did…

Kevin was a surprise guest at a special screening of Youth in Revolt, a comedy starring Michael Cera, Zach Galifianakis, Ray Liotta and newcomer Paula Doubleday, at the Elgin and Winter Garden Theatre.

"Kevin came in a side door to let the stars of the movie be in the spotlight," reports a fellow premiere-goer. "Backstage before the movie started, he talked with the cast and the filmmakers."

Despite having woken up that day at 7 a.m. for a full day of shooting, Jonas showed no signs of sleepiness. He was dressed in jeans, V-neck T-shirt and tuxedo jacket.

"He was chatting about his engagement, how he loves golf and about how he has a house in L.A. but their home base will always be Texas," the source said.

Meanwhile, the youngest brother of the musical trio, Nick, celebrated his 17th birthday with a new piano. People magazine reports the family surprised him by buying the hotel piano that he used to write "A Little Bit Longer." Camp Rock producers gave him a ping-pong table.
