Lewis Hamilton and Nicole Scherzinger at "Goldenes Lenkrad" automobile awards at Ullstein Halle, Berlin, Germany - 051108

The 30-year-old singer is adamant that she doesn't tolerate womanisers and even though she loves her Formula 1 boyfriend, she would dump him straight away if he ever strayed.

She says, "We really trust each other but I would draw the line if he cheated. Any woman with self-respect and self-worth wouldn't tolerate that."
