Gilles Marini and Jerry O'Connell strip nearly-naked on 'Ellen,' for a good cause
Somehow this has something to do with raising money to support National Breast Cancer Awareness. So it's for a good cause. But we're not sure that's the real appeal of these video segments, which previously featured Liam Neeson and Maksim Chmerkovskiy.
Despite his actually naked appearance in the "Sex and the City" movie, Marini seems a bit embarrassed by the whole thing. But O'Connell hams it up, shaking his booty and getting spanked by audience members on his walk to the dunk tank. It probably helped that his wife Rebecca Romijn and "Mockingbird" co-star Portia de Rossi were there cheering him on. Watch both videos below:
