Rumours rife after couple unfollow each other on Twitter and also stayed away during each other's US Open matches recently
Tennis stars Maria Sharapova (27) and Grigor Dimitrov's relationship is reportedly on the rocks. Recently, the tennis players allegedly unfollowed each other on Twitter.
The tennis couple have been dating since late 2012, but a couple of recent incidents suggest that the two may have called it quits.
Both players follow less than a hundred people on social networking site Twitter, so when both of them disappeared from each other's list of followers, fans and critics were quick to take notice.
Then, recently both were even noticeable absent in the stands when either of them played in the US Open recently.

In a recent interview with W magazine, Dimitrov (23), who was once rumored to be dating Serena Williams had said of his romance with Sharapova: "It's the best thing that could ever happen to you.
But it's not easy. With travel, media, the gym, practice, we hardly see each other. On the other hand, we truly understand each other. We know what sacrifice is."
