Nicole Scherzinger is said to be secretly dating Maria Sharapova's ex, Grigor Dimitrov. After breaking up with her longtime boyfriend, Lewis Hamilton, it looks like the "Don't Hold Your Breath" singer looks has moved on with a younger sportsman who's 13 years her junior.

Reports have it that Scherzinger, 37, has been seeing Dimitrov, 24, after the latter split with his girlfriend of two years, Maria Sharapova.  According to some gossip sites, the rumored pair apparently agreed to keep their new romance confidential after their past high-profile relationships. Scherzinger's dating news reportedly hit Hamilton, and he was said to be upset about it after realizing that he needs her more than ever. He had been trying to communicate with her for several weeks now, Daily Mail reports.

"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," one source told The Sun of the Pussycat Doll singer's secret relationship with the tennis ace.

Earlier this month, Hamilton and Scherzinger's dating rumors quickly spread online after the ex-couple was seen attending a John Newman gig at The Box. Although they were not seen together, their presence in the same venue sparked reconciliation rumors between the two. Reps for the "Don't Cha" hitmaker clarified that the duo's presence in the venue was a mere coincidence.

Before the new reports surfaced, the 37-year-old was seen kissing Swiss footballer Pajtim Kasami, 23, in Greece during her birthday in June.

Reports claim that Scherzinger seems to have a flare for dating famous younger men. This year, it was rumored that she had a short-lived romance with singer, Ed Sheeran, 24. Meanwhile, Hamilton was romantically linked to "B*tch Better Have My Money" singer, Rihanna, but their closeness seemed to have meant nothing as their romance rumors faded quickly.
