Nicole Scherzinger and Lewis Hamilton over

Nicole Scherzinger and Lewis Hamilton ‘end four-year romance’ 

The couple have been battling relationship woes for months after work commitments put a strain on their romance – but it has now been revealed they have finally split for good.

A source told The Sun: ‘Nicole and Lewis have tried to make it work but realise it’s just not happening so have called it a day once and for all.’

It is thought to be down to their hectic work schedules which often see them on opposite sides of the world.

As well as being tied up with her duties on X Factor US, 33-year-old Nicole has this year been promoting her debut solo album Killer Love and filming her cameo role in Men In Black III.

Meanwhile, Hamilton has been touring all ends of the globe with his F1 racing team McLaren.

The source added: ‘Although they came to an amicable decision, Nicole is actually devastated about it. She thought Lewis was the one.’
