He has dated Maria Sharapova and Serena Williams. Now it seems to be love-all between tennis player Grigor Dimitrov and Nicole Scherzinger.

The pair were seen kissing as the 37-year-old pop singer - former flame of Lewis Hamilton - accompanied the 24-year-old sportsman to a tournament in Australia.

They were first linked last July but these pictures appear to be confirmation that they are now an item.

Former Pussycat Dolls singer Miss Scherzinger split from Formula 1 champion Hamilton, 31, after a seven-year relationship last February and appears to be bouncing back with the younger man.

Dimitrov, ranked 28 in the world, was knocked out of the Brisbane International by Roger Federer, 34, yesterday. He is still competing in the doubles section and will play his semi-final match today. The Bulgarian, who has been called the sexiest man in tennis, is believed to have grown close to Serena Williams in early 2012 when they shared the same coach.

Dimitrov later joined a new coach and at the same time dumped Miss Williams, 34, and began to date Maria Sharapova, 28.

After splitting from Miss Sharapova last year he began dating Miss Scherzinger, who has been at the Australian tournament all this week supporting him.

"They're completely besotted. But they're careful not to be pictured together because they don't want the pressure of the relationship in the public eye," a source said in November.

Dimitrov has earned around £4million in prize money, while Miss Scherzinger is worth some £5.5million. Her agent would not comment last night.
