Lately, with the pics I saw of mirka (Federer's) from the Laureus Awards... I'm thinking she's a total babe. And she's smart. (Plus I think it gives a little bit of an insight into what Roger is like...you know?) She knows the game, she can help him more than some pretty blonde bombshell.
Of course, this does not include other pretty blonde ladies on the scene... like Petra Bjorkman, LOL! I dare say... Jonas married up!
