[Flynet, WENN]Bar Refaeli at the Sports Illustrated Swimsuit Edition party at LAX nightclub in Las Vegas (2/12)

People magazine is claiming that Leo DiCaprio and his impossibly-hot girlfriend Bar Refaeli broke up. When reached for comment, Leo's penis said, "NOOOOOOOOOOOOOO!!!!!!!" A source told the magazine:

"They're taking time off for the time being, they've split. It could just end up as a break but for now they're doing their own thing."

That much was certainly apparent over the weekend as the Israeli-born Sports Illustrated swimsuit model, 23, walked the red carpet at Hollywood Life's 11th Annual Young Hollywood Awards solo, refusing to speak about DiCaprio, while the Titanic star, 34, hit the hotspot Avenue in New York City, where he was seen chatting with another woman.

"He was standing at the bar in front of everyone talking to a girl the entire night - and it wasn't Bar," says one onlooker. "It was in no way behavior for a guy who has a serious girlfriend."

According to a Refaeli source, the model's desire to get serious may have caused the actor to have doubts about their relationship. "She wanted to move faster than he did, she wanted to move in together," the source says, "so he broke it off."

Considering Bar and Leo were seen together at a Barnes and Noble in L.A. last night (see here), who knows what to make of this story. The only thing we can be sure about -- and I have multiple sources that can confirm this -- is that I really, really, really want to bone Bar Refaeli. Call me Bar. We don't have to rush into things. Maybe I can just stare at you a little and see where that takes us.
