Nicole Scherzinger is dating Pajtim Kasami.

The 37-year-old singer - who split up with Formula One driver Lewis Hamilton earlier this year - has been pictured kissing the 23-year-old Olympiacos football player while out in Mykonos, Greece, to celebrate her birthday, although a source has insisted they're just friends.

Speaking to Mirror Online, the source said: ''Nicole is on a girls' holiday celebrating her birthday. He is a friend of a friend who was in Mykonos as well.''

While the 'Poison' hitmaker is having fun with a new man, she and Lewis are still ''friends'', having been on and off for seven years, before they called it time in February, and the racing driver took to Instagram to send his ex a heartfelt birthday message yesterday.

Along with a loved-up shot of the pair taken while they were still together, 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.''
