Nicole Scherzinger 'dumps Lewis Hamilton after he refused to marry her and start a family'.

36-year old singer Nicole Scherzinger has sensationally split from Lewis Hamilton, according to a new report.

The shock separation comes after seven years of dating which has been marred by both public highs and private lows punctuated by periods apart.

In a story published by The Sun, it is alleged that the 36-year-old singer allegedly called time on the romance after the 30-year-old Formula One champion refused to marry her and start a family. 

The source told the paper's Dan Wootton: 'They've been fighting for months but things had got much worse.

'She finally had enough. Nicole knew Lewis had no plans to marry her, she's completely gutted and feels lost about her future.' 

The paper went on to claim that last week both Nicole and Lewis denied rumours that their relationship had petered out.

The pair have not been seen together in a few weeks and Lewis' last Instagram post of them both was a month ago with Nicole's just a few days before. 

In December, Lewis revealed that he and the Cats star had never talked about marriage because they were continuing to juggle their work balance.

In a candid interview with The Sunday Times Style magazine, he confessed: 'We're in a good place. She's such a hard worker, and we inspire each other. But I don't think we've ever really discussed marriage. 

'We're very much aware of the time together, and how precious time is. I think naturally, at some stage, that becomes a step. But we're trying to support each other while we do things we love.' 

Originally going public with their relationship in 2007, the couple briefly split in January 2010 when they had been together for 20 months, before later reconciling.

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

But the pair separated once again in July 2013, which prompted Nicole to break down in tears during her tenure on the X Factor. 

However, by February 2014 things were back on... until now. 

Being much younger Lewis may not be ready to settle down just yet?
