Grigor Dimitrov may be angering his ex Maria Sharapova by PDA-ing all over Brisbane with his new girlfriend Nicole Scherzinger. Looks like Grigor Dimitrov couldn't hold back on expressing his love towards his new girlfriend.

According to Hello! Magazine, "Nicole, who was supporting her man at the Brisbane International tournament, looked very-loved up as she and Grigor strolled through the tennis grounds. Walking hand-in-hand, the pair stopped to kiss before Nicole, 37, affectionately wiped her lipstick mark off her boyfriend's lips."

Grigor Dimitrov had a strong start to the new year, thanks to all the support from Nicole Scherzinger. By winning his first game in Brisbane, the Bulgarian was to show his new girlfriend that he can be the champion that he always dreamed of.

According to Fox Sports, "Scherzinger, who's expected to release her third album this year, has apparently flown to Brisbane to support world No. 28 Grigor Dimitrov, whom she is reportedly dating."

Well it's a good thing that "Dimitrov defeated fifth-seeded Simon 6-3 7-6 (12-10) to reach the Brisbane International second round."

After his breakup with the tennis star Maria Sharapova (who undoubtedly was much more successful than him), Grigor Dimitrov has been concentrating on tennis as well as his new relationship with Nicole Scherzinger.

The last picture uploaded on his account is of his Rolex watch two weeks back. And the fans are wondering if he accompanied his new girlfriend Nicole Scherzinger on her recent trip to Hawaii.

His professional career is already looking up. According to Tennis News, "The 24-year-old whose ranking has sunk to 24th after hitting 11th on the ATP list at one point, seems to be enjoying his work with new coach Franco Davin, sacked by Juan Del Potro when the Argentine realized he needed months and months of rehab on another wrist problem."

In fact, Grigor Dimitrov has been looking happier than ever on his Instagram. According to a source from Perez Hilton, "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 already both benefiting from their relationship.
