Nicole Scherzinger has reportedly split with tennis player Grigor Dimitrov amid reports her ex Lewis Hamilton has moved on.

The 37-year-old singer was first linked to 24-year-old Grigor back in November, before the pair went public with their romance in January at a tennis tournament in Australia.

While things were originally going well for the couple, Nicole's desire to start a family apparently caused things to end with her sportsman beau.

"Nicole is at a different stage in life to Grigor," a source told Britain's The Sun newspaper. "She really likes him but wants to settle down - something he’s not quite ready for.

"It’s the situation she had with Lewis (Hamilton), which is why that relationship stalled. She’s aware she is not getting any younger and wants kids."

Nicole split from Formula 1 driver Lewis in January 2015 after a seven year on/off romance, with their disagreements over settling down and having children also said to have led to their break-up.

Grigor was also newly single when he embarked on his romance with Nicole, as his two year relationship with tennis star Maria Sharapova ended in July.

Despite Nicole and Grigor's split, Nicole is apparently still hoping that the Bulgarian will make a dramatic gesture to get her back.

"She hopes he might come back with a proposal," the source added to The Sun.

Hamilton's romantic life is also headed in a new direction as he reportedly hit it off with supermodel Petra Nemcova after they sat next to one another at the Laureus World Sports Awards.

The pair were spotted leaving their Berlin hotel together the night after the event and were spotted on a date, according to The Sun.

Meanwhile, Nicole will be joining the upcoming Dirty Dancing revamp from U.S. TV network ABC.

She will portray Penny Johnson, the role made famous by Cynthia Rhodes in the 1987 film.

Little Miss Sunshine star Abigail Breslin will tackle Jennifer Grey's Frances 'Baby' Houseman character, while Debra Messing will play mum, Marjorie, and Colt Prattes will take over the part of Johnny Castle from the late Patrick Swayze.
