Guess we should all have seen this coming: boy makes fun of pretty girl, pretty girl then shows up at his tennis match, and then the two party deep into the night, singing karoke. He probably showed her his racquet. It’s totally on: Maria Sharapova and Novak Djokovic. If one NY tabloid has it, no big deal; if both have it, well, you know it’s true.

Also, there’s something about Federer partying with Gwen Stefani and her husband.
