Ashlee Simpson Pictures Kissing Vincent Piazza

Ashlee Simpson and her main man Vincent Piazza took a Sunday stroll around NYC. The happy couple was together again after first being spotted publicly displaying their affection in the Big Apple two weeks ago. In the intervening days, Ashlee went home to LA to spend time with her son, Bronx, and ex Pete Wentz, who's rumored to be moving on himself with Michelle Trachtenberg. Vincent, meanwhile, continued to shoot his hit HBO series Boardwalk Empire. Despite the show's setting in Atlantic City, NJ, Vincent and his costars frequently film around New York's boroughs. It's a convenient location, since Ashlee's spending time in the city working on her new line for tweens with her big sister Jessica.
