Ana and Novak not involved.
From his site:
"Two days in Belgrade Djokovic is going to spend with his family. "I want to rest and be with my family, aunt and sisters who came from Geneva, and with my girlfriend," said Novak but didn't want to reveal the secret about her name. It's only known that she isn't Ana Ivanovic".
That two-timing bastard -LOL
I think its better that them two are just friends - it would only take away their concentration from tennis - besides it gives me more of a chance, ")
