The former Pussycat Doll and X Factor judge has been joined by footie player Pajtim on the Greek island of Mykonos where she's celebrating her 37th birthday.
Nicole was spied locking lips with 23-year-old Pajtim, a Swiss footballer, while standing on a hotel balcony, sparking rumours of a new romance…
While she was sunning herself on holiday, the star's ex-boyfriend, Formula One racer Lewis Hamilton, 30, sent a message to mark her special day.
He wrote: "Dear friend, Through the years we shared a lot, I wouldn't have changed a thing. All the experiences made me the man I'm proud to be right now. The memories together will never be taken away no matter how old we get and I'm thankful for the time we had.
"I'm wishing you the Happiest of Birthdays, and may God continue to Bless you in all that you do. #waayyyupstayblessed."
