Four years after his wife, Ann, donated her kidney to him, George Lopez worked the crowd at the National Kidney Foundation's "KEEP it Hollywood" event at Guy's North in Studio City, Calif., on March 13. "He looked like he was in excellent shape and spirits!" an onlooker says. The party, which raised awareness for kidney disease, also included celebrity guests Aimee Garcia, Romany Malco, and Dominique and Chelsea Swain on its VIP list.
