George Lopez and Sandra BullockSandra Bullock, don't worry about your wandering husband Jesse James. Your buddy George Lopez has your back. Unless it comes to a fight.

"She's my fairy godmother," said Lopez when asked why he's been visiting Bullock recently. "She knows how much I care about her. And, you know, when times are tough, friends step up." The remarks by the frank-talking but supportive 'Lopez Tonight' star aired during an interview on E!'s 'Daily 10' show Thursday night.
