Maria Sharapova may be dating a new man as her ex Grigor Dimitrov is starting a new relationship with Nicole Scherzinger. Looks like the Russian beauty isn't letting her petty ex boyfriend drama get to her!

According to Daily Mail, "Maria Sharapova appeared unfazed by the rumours as she enjoyed a casual outing with a male friend in New York City on Wednesday evening... The pair were deep in conversation and at one point her friend even reached up to help her sweep a stray strand of hair out of her eyes."

Looks like the walk through New York was quite romantic for Maria Sharapova.

Meanwhile, she must be eagerly avoiding her ex Grigor Dimitrov's Instagram, in which he has been looking happier than ever. His new relationship with Nicole Scherzinger might be the big reason for the smile on his face.

According to Perez Hilton, "Nicole Scherzinger has been cozying up to 24-year-old tennis pro Grigor Dimitrov since July. The pairing comes just nine months after Nicole and her long time boyfriend Lewis Hamilton parted ways."

A source commented, "They're completed besotted with each other. But they've been careful not to be pictured together because they don't want the pressure of the relationship being in the public eye."

Sounds like Grigor Dimitrov and Nicole Scherzinger are ready to start their relationship.

In fact, the Bulgarian tennis player might have regretted his relationship with Maria Sharapova, according to the most recent interview. While Maria Sharapova is living the high life having totally gotten over Grigor Dimitrov, the Bulgarian may still be thinking about his ex girlfriend.

According to Tennis World, Grigor Dimitrov reflected about the past season and revealed that he does not want to make the same mistakes he made. "... I lost a little bit of confidence, I changed a my racquet and I had some changes off court.... I started to make things wrong in practice, my fitness level wasn't good and so I didn't play a very good tennis. Hopefully I'll learn quite enough from it and I hope I don't make the same mistake in 2016."

Maybe keeping a relationship with Maria Sharapova was the "mistake" that he made in 2015.

The truth is, some men can't handle having a super successful girlfriends. In just one season, he slipped in ranking from world number 11 to 26. Talk about a downward spiral. Let's hope that having a girlfriend like Nicole Scherzinger means that he won't feel threatened in his career.

Do you think Grigor will ever get to Maria's level? Let me know in the comments below!
