Lewis Hamilton and Nicole Scherzinger at the Men in Black 3 film premiere
Nicole Scherzinger's on/off relationship with Formula One champ Lewis Hamilton has run out of gas, according to reports.
The X Factor judge and the racing driver have been a couple for over five years, but have split up several times during their romance.
Now the couple has decided to call it a day once again after failing to make their relationship work because of their hectic schedules.
A source tells 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."
The break-up comes just days after Hamilton hinted the pair could be heading up the aisle soon. He said, "We've been together for five years, which is quite a milestone. But hopefully in the near future."
Nicole is back in the U.K. filming the audition round for the latest series of The X Factor, which sees former judge Sharon Osbourne return to the panel, alongside original Louis Walsh and Simon Cowell's replacement Gary Barlow.
