Maria Sharapova and Grigor Dimitrov might appear to have it all but the couple's relationship is reportedly on the rocks. Recently, the tennis players allegedly unfollowed each other on Twitter.

Since they only follow less than a hundred people, fans were quick to point out that they removed each other from their "Following" list. However, some say that the two were not really following each other on Twitter.

In a recent interview with W magazine, the rising tennis star who was once rumored to be dating Serena Williams talked about his romance with the Sugarpova candy empire owner.

 "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," he said.

The 23-year-old appears to be determined in keeping his relationship with Sharapova as he described himself as the "initiator" their romance. In his interview with Vogue for its September issue, he disclosed how their relationship started.

"I sent her a funny email and she replied, and back and forth, and that was it," said the Bulgarian champ who admitted to crushing on Sharapova at the early age of 14 years old when he first saw her battling with Lindsay Davenport.

She is very strong-minded and knows what she wants. It's why she's the best at what she does," he gushed.
