I also heard that...I think once was at one of the US masters earlier this year (Indian Wells or Miami...and apparently he was biting his nails cos he was nervous for her) and then I also heard that about Roland Garros, since he was there even though he wasn't playing...this is just what I heard...I personally think it's either bs or something that's been completely blown out of proportion...since then he and her have both said they're single and nothing more's been heard from what I can tell
Rafael could not be seriously dating Sharapova or Kirilenko. I mean, the kid doesn't even speak English!!!!
I met him in Toronto, and the only thing he knows how to say in English is 'thank you' in case someone wishes him good luck. And one other thing, I find it really hard to believe that Rafael would hang out with anyone who isn't Spanish. For some odd reason the Spanish players tend not to 'mix' themselves with other players. From what I observed in Toronto, Rafa pretty much hangs out with his uncle/coach Toni, Carlos Moya, Moya's coaches, JC Ferrero, David Ferrer, Feliciano Lopez, and Fernando Verdasco. The only time I saw him hanging out with someone who wasn't from Spain was when he was practicing with David Nalbandian who is also Spanish-speaking.
The only Spaniards who have buddies outside the Spanish Armada are Ferrero and Moya. They are both good friends with Marat Safin (but then again who isn't?). And Moya seems to be pretty close to Guga Kuerten (Guga has even said before in an interview that Moya is one of his best friends on the tour).
