The X Factor judge Nicole Scherzinger has been left devastated after splitting from Formula 1 ace, Lewis Hamilton.

The couple called off their five-year romance because of their busy work schedules, after their strained holiday in Capri, Italy.

A source told the Sun that the singer is heartbroken about the split as she thought Hamilton was 'the one' but it didn't work out.

The insider said that the high profile couple actually broke up around a month ago and has been keeping it quiet since then.

It was revealed to the publication that only a few close friends and family knew and they've been comforting both of them.

The insider added that Scherzinger had a gig in Sardinia on Monday and she is throwing herself into work to forget the pain of the break-up.
