Note to Sam Mendes: Your wife, Kate Winslet, is starting to confuse you with her on-screen husband, Leonardo DiCaprio. The actress, who’s starring in Revolutionary Road with Leo, has been spending so much time talking about the movie — and her co-star — that he “feels more like my husband than my real husband,” she tells Britain’s GMTV. “I’m talking about him so much.” Meanwhile, real-life hubby Sam directed the duo in the drama. But he’s got nothing to worry about. Leo recently admitted about kissing Kate, “It’s like kissing a family member.”
