Former X Factor judge Nicole turns 37 today (29 June), and Formula One driver Lewis sent her a public message via Instagram this morning.
He began: "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."
Lewis and Nicole split in February. At the time, former Pussycat Doll Nicole said she was "devastated" by the break up, but explained it was a mutual decision.
'Your Love' singer Nicole opened up about their split last month, telling People magazine: "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."
