You wouldn't think a pro athlete and a vodka aficionado would have much in common, but that doesn't seem to be the case between tennis star Maria Sharapova and comedian Chelsea Handler.

The No. 3 ranked women's player was a guest on Chelsea Lately earlier this year and it seems like the two have remained friends since the show. Chelsea was spotted in Maria's box cheering her on during her first round match at the Olympics yesterday!

It seems like having Chelsea in her cheering squad helped because the Russian athlete easily won her match! "Chelsea called me last night and asked if she could come," said Maria to commentator Rennae Stubbs after the match. "I was just worried about what she was going to do once she was in the box!"

Check out Maria's interview with Chelsea and the comedian's shout to Maria for winning the French Open last June below! Her own line of candy she was promoting called Sugarpova will be officially released on August 20!
