Nicole Scherzinger and Lewis Hamilton split again

X Factor judge Nicole Scherzinger and Formula 1 racing driver Lewis Hamilton have split after five years together.

Nicole Scherzinger, 34, and Lewis Hamilton, 28, 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.”

The sad news comes just a matter of weeks after Lewis Hamilton hinted that he was planning to propose to Nicole Scherzinger.

Lewis Hamilton 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 Scherzinger has regularly been seen supporting Hamilton 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 Scherzinger has been kept busy with auditions in locations including Glasgow, Dublin and London, while Lewis Hamilton 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 Scherzinger 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.

Nicole Scherzinger and Lewis Hamilton met at the European Music Awards in Munich in November 2007, before going public at the Monaco Grand Prix six months later.

In July 2011 there was unconfirmed speculation the couple had become engaged.

Nicole Scherzinger and Lewis Hamilton briefly split in January 2010 when they had been together for 20 months, before later reconciling.

The couple then split again in late 2011, before giving their relationship another go in early 2012.

Nicole Scherzinger is expected to make an appearance at the X Factor auditions in Cardiff later this week.
