The 28-year-old Russian star began dating Bulgarian tennis player Grigor Dimitrov in 2013, but he has now confirmed their two-year romance is over.

He says, "Our paths split. We experienced wonderful moments together. I wish her much happiness and success in life and in tennis. Now I'm concentrated entirely on the game and I'm sure the results will soon be seen. This is the summer of the new beginning for me."

Sharapova was previously engaged to marry Slovenian professional basketball player Sasha Vujacic, but they parted ways in 2012.
