Joe Jonas, 30, was feeling a little feisty on March 6. While taking a walk with wife Sophie Turner, 24, in the Los Angeles neighborhood of Studio City, the singer gave her derriere a love tap! Befitting Joe’s playful mood was his T-shirt, which displayed a print of Bart Simpson kicking back with the slogan, “Genius at work…Do not disturb.” Sophie’s top paid homage to another icon, David Bowie, and she kept the rest of her outfit casual with athletic short shorts and pink-lace sneakers.
