Rafael!

RAFAEL Nadal has a girlfriend, but it didn't stop him from flirting with Shakira the other night. According to the New York Post, before his loss in the US Open semi-final, the Spanish ace -- who's been dating high school sweetheart Maria Francisca Perello, for three years -- was at Nobu Tribeca, where the Colombian pop star was promoting her new album, "She-Wolf." "They were each there with a friend, but once they started talking, they moved to a table alone for some privacy," said one witness. "There was flirting going on." Uh, WHAT?! I thought they both had significant others. I mean, I'd probably flirt with Rafael or Shakira for that matter...so, I won't pass judgement. Have you seen her She-Wolf video? YOWZA. (That's right, I said YOWZA)
