So far, the girls have twitpic-ed some really hawt photos as well as some pretty interesting updates too e.g. Wozniacki got an invitation to the American Embassy to meet Arnold Schwarzenegger and Azarenka revealing her 'betting habit' :D
Wozzie in Liverpool jersey with an autograph specially signed for her by her favourite player, Fernando Torres.
Hopefully these girls will convince more top players to start tweeting soon namely Maria Sharapova and Ana Ivanovic.
