Grigor Dimitrov is letting his new girlfriend Nicole Scherzinger party without him as he revs up for the next Grand Slam tournament, French Open 2016. While he is hitting the balls in Mexico right now, Nicole Scherzinger is furthering her career by partying it up in Los Angeles.

"She spent much of last week joining the style elite on the front row at New York Fashion Week. And rubbing shoulders with a chic crowd has clearly had an impact on Nicole Scherzinger, who put on an incredible display as she partied the night away at Warwick nightclub in Los Angeles on Sunday," according to Daily Mail.

Sounds like they taking things easy and chill as they start this new relationship.

But there is a slight chance that Nicole Scherzinger is just too busy for her new boyfriend Grigor Dimitrov. Even on Valentine's Day, she didn't spend the whole day with the tennis star, instead choosing to pay tribute to Lionel Ritchie at his gala.

But this may be a good thing as Grigor Dimitrov concentrates on training hard for French Open 2016.

"Nicole Scherzinger, Demi Lovato and Ellie Goulding were among the stars who turned out on the red carpet to pay tribute to Lionel Ritchie... Nicole looked like the Pussycat that got the cream in a stunning black dress off one shoulder," according to Mirror UK.

Bulgarian tennis star, instead of showing off his new girlfriend on Instagram, chose to show how hard he is working on his game. Knowing that he did not have the most successful campaign at Australian Open 2016, he must be ready to work doubly hard this year.

Meanwhile, his girlfriend is keeping herself busy by making appearances at all the galas, parties and Hollywood engagements. Maybe this is her way to keeping herself out of her boyfriend's way as he trains for French Open 2016.

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.
