Guess his breakup with Bar Refaeli was legit.

At the very least, they're taking time off and both are cavorting with others. The hot Israeli model was recently seen with Ricardo Mansur. Now it's Leo's turn.

Leonardo DiCaprio has been busy on the London party scene and has now apparently hooked up with Ashley Roberts of the Pussycat Dolls, reports The Sun.

A star who does not exactly gravitate to the cameras (novel concept), Leo attended a celebrity-packed Cartier International Polo event over the weekend.

That's where he got cozy with Ashley.

Ashley Roberts cozies up to Leonardo DiCaprio in the UK.

“They were getting on like a house on fire, drinking bottles of champagne and tequila. They were so close at one point she was almost on his knee,” says The Sun.

Whatever comes of this hookup, don't expect to see The Departed star strolling down Sunset Boulevard with the Pussycat on his arm. No, he will keep us guessing.

This is surely not going to go over well with Kimberly Wyatt and the rest of her band mates. You know how jealous they can get about ... anything. Those Dolls.
