Despite rumors of a possible break up, the singer's reps have now confirmed that reports of the pair's split is completely untrue.
According to The Sun newspaper, the former 'Pussycat Doll' ,37 had parted ways with the sportsman because she was ready to settle down.
A source reportedly told the publication: "Nicole is at a different stage in life to Grigor. She really likes him but wants to settle down – something he’s not quite ready for. It’s the situation she had with Lewis, which is why the relationship stalled. She’s aware she is not getting any younger and wants kids."
Nicole and Grigor reportedly began dating in back July 2015, shortly after he broke off his two-year romance with fellow tennis star Maria Sharapova. The Bulgarian hunk is 13 years Nicole's junior and the brunette beauty went public with the World no 28 as she was pictured kissing him at a tournament in Australia.
Nicole used to date Formula 1 champ Lewis Hamilton on and off for seven years, with both parties said to be heartbroken when they went their separate ways in May last year.
