Kate Winslet recently explained to Marie Claire UK why she's such good friends with Leo DiCaprio: it's because they've never done the deed. Indeed, sex ruins everything!

“I think the reason that friendship works is because there was never any romantic thing. It’s so disappointing for people to hear that, because in the soap opera of the Kate and Leo story we fell in love at first sight and had a million snogs, but actually we never did. He always saw me as one of the boys. I’ve never really been a girly-girl.”

Really? Never? But then again, Kate isn't Leo's type.
