While Nick Jonas is focused on his new solo tour and Kevin is focused on his new life with his wife Danielle, Joe has been trying a little of everything -- from guest judging American Idol to jamming alongside Switchfoot's Jon Foreman at the ESPN National Championship Tailgate at the Rose Bowl Stadium.

Switchfoot played "Mess of Me" and "Dare You To Move" and other hits from their album, Hello Hurricane -- and Joe joined in! Check out that passion -- now that's a real rockstar!
