Nick & Joe Jonas Wish 'Big Bro' Kevin a Happy 33rd Birthday

Kevin Jonas is ringing in his 33rd birthday Thursday (Nov. 5) with the help of his brothers.

Joe Jonas' tribute put a smile on fans' faces when he asked Kevin an important question about his smile. "Happy birthday @kevinjonas love you like a brother. Miss you mate! Can’t wait to hang when it’s time!" he captioned the throwback photo, which he tagged at Hot Topic Willowbrook in their home state of New Jersey. "P.S. I can’t tell if that’s a mystery tooth or gum in your mouth."
