Nicole Scherzinger and her Formula 1 star boyfriend, Lewis Hamilton have split - just days after he hinted that he was ready to propose.
The couple - who have been dating for five years - have blamed their hectic work schedules on their split and the fact they live in different countries.
US-based Nicole, 35, has been busy back in the her judge's seat on 'The X Factor' as this year's auditions get underway, whilst Lewis, who lives in Switzerland, has been taking part in F1 races around the world.
A source told The Sun: “It’s so hard to keep up a relationship when they’re barely in the same country as each other.
“Both have supported each other in their careers and will continue to do so. But the nature of their work ultimately cost their relationship.”
Just last week, Lewis, 28, hinted that he was ready to pop the question to the former Pussycat Doll.
“We’ve been together for five years, which is quite a milestone really," he said. “But hopefully in the near future. Maybe before we get to six years.”
The pair began dating in 2007 after meeting at the MTV Music Awards. The couple briefly split in October last year following claims Nicole and Chris Brown were spotted getting cosy at a LA nightclub.
