Ellen Dunks Mario Lopez for Charity

Rosie O'Donnell had a thing for Tom Cruise. So why shouldn't Ellen DeGeneres enjoy a shirtless Mario Lopez?

The daytime talk-show host told her studio audience Wednesday that every time Lopez stops by the show, she tries to get him to take his shirt off. Wednesday she succeeded, all in the name of charity.

Lopez stripped down and agreed to be dunked by DeGeneres to raise money for Susan G. Komen for the Cure in honor of National Breast Cancer Awareness month. DeGeneres spent a fair amount of time checking out Lopez's body before dunking him in the tank and raising $20,000.
