Lewis Hamilton shared a touching tribute to ex-girlfriend Nicole Scherzinger on her 37th birthday on Monday (29.06.15).

Although the couple called time on their seven-year on/off romance in February, they are clearly still on good terms and the 30-year-old Formula 1 ace posted a sweet picture of them together on his Instagram along with a gushing message.

He wrote: ''Dear friend, Through the years we shared alot, 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 (sic).'

The picture shows the former couple cuddled up together in matching black hats.

Singer Nicole is currently enjoying a relaxing birthday in Mykonos, Greece, after flying out to celebrate her big day at the launch of English businessman Joe Fournier's club Bonbonniere on Saturday night (27.06.15).

While Lewis has been linked to Kendall Jenner since the split, the pair have remained amicable with Nicole previously hinting that they had both become ''complacent''.

She explained:''Sometimes people stay in relationships because they get complacent, because it's comfortable for them, because they don't want to be alone.

''It's a new chapter in my life. I'm going through a very transformative time in my life.''
