Kate Winslet's sex-positive, clothes-allergic career emerged from its most severe test to date in Revolutionary Road: It was there, the actress admits in a wrenching confession to ET, that her husband sternly insisted that he share her with Leonardo Di Caprio.

In fairness, her husband, Sam Mendes, was the director — a first for Winslet that seemed to bother her in ways that her Titanic leading man Di Caprio more readily shrugged off:

Did some of those intimate scenes get a little awkward? "Not a problem in this department," Leo says. "It was right for the characters."

"You know what? Yes, it was (awkward)," says a candid Kate. "I did feel weird about it — [but] you get over that quickly. You really have to." She adds that her husband "really treated me like the actress playing [the character]," and that during one of their more heated scenes, "Sam would sort of yell from the other room, 'No, Leo really grab her thigh! Really grab her thigh!' I thought, 'This is really strange, but I'm gonna go with it.'"

Kinky! Not to mention an improvement over those James Cameron days, when "grab her thigh" was simply something the Titanic taskmaster disgustedly spat at on-set paramedics every time the fragile Di Caprio cramped up while treading water for six hours on end.
