The X Factor judge and the racing driver, who went public with their romance back in 2007, are believed to have ended their relationship as their busy work schedules meant they just didn’t get to see each other.
A source said: “Nicole is just so heartbroken and completely devastated.”
A spokesperson for Nicole confirmed the split to the online version of the publication.
The sad news comes just a matter of weeks after 28-year-old Lewis hinted that he was planning to propose to Nicole, 34.
He said: “We’ve been together for five years, which is quite a milestone really. But hopefully in the near future. Maybe before we get to six years.”
Nicole has regularly been seen supporting Lewis at his various Grand Prix commitments, but admitted previously she is only there for her beau, rather than knowing anything about the sport as a whole.
She said: “I only go to a Grand Prix to support Lewis. I am in awe of Formula One because there is so much money, technology and talent, but as for the racing, it really is like trying to understand rocket science when I’m there, trackside.
“For me there’s only ever one winner and a lot of people would agree with me on that – Lewis is the best.”
But since recommitting to the X Factor this year, Nicole has been kept busy with auditions in locations including Glasgow, Dublin and London, while Lewis has been concentrating on his racing career.
The last time the couple were pictured together was at the Canadian Grand Prix in Montreal on June 10th.
Since then, Nicole has gone solo at various events including Wimbledon last week and the Summer Music Festival in Rome, Italy, where she put on a stunning performance last week.
