As always, James, 41, was a tad more taciturn. Asked what he likes best about Von D, 28, the motorcycle mogul offered one word: "Everything." The tattooed duo proved inseparable over a PDA-filled Labor Day weekend in L.A., stealing kisses over chips and salsa at Pinches Tacos and buying his and hers "Rebel with a Cause" T-shirts at the J. Gerard Design Studio and Peace Gallery before the father of three headed back to Austin to get his kids Sunny, 6, Jesse Jr., 13, and Chandler, 16, ready for the school week.

Von D may have fallen for him "when we were playing Scrabble," she says. "We both realized how nerdy we were!"
