And the Oscar for Biggest Flirt goes to... Chris Brown!

Chris attended Elton John's star-studded Oscars after-party without Rihanna on February 25, and he was reportedly flirting with other women, according to Us Weekly.

In fact, Chris was "bombarded" by fans who wanted to take pics with him, and one of those fans especially caught his eye.

"He told a tall blonde woman who asked for a photo, 'You're gorgeous,'" says a source. Keep it in your pants, Chris!

Chris reportedly was chain-smoking near the bathroom for a while, and when he headed to the bar, he was "super-social" with everyone there and was talking "non-stop."

"He was the life of the party," says an onlooker. "He looked so happy to be getting such positive attention from guests."

At one point, Chris was asked about his recent vacation — which he spent with Rihanna last week in Hawaii for her birthday — and he said, "Hawaii was great!"

Chris also saw Kim Kardashian at the party, and the two reportedly spoke for about ten minutes. New besties alert?

Chris wasn't at the Oscar ceremony, but his name was mentioned during the telecast by Seth MacFarlane, who made a joke comparing Chris and Rihanna's relationship to the violence in Django Unchained.

So is Chris's partying going to cause tension between him and Rihanna? We shall see!
