Hewitt got caught banging Golovin. It's his fault.
That's what I read as well. Don't know if it's just a silly gossip, though.
Not unlike Flavia Penetta catching Moya humping a groupie in his hotel room.
Anyways, Kim is a happy mother right now, and rumour has it that she might well be considering a come-back on the tennis courts as well (would be great considering the dreadful state the WTA is in right now). Whatever she'll be doing, I wish her all the best.
