Washington, Dec 15: Pussycat Dolls star Nicole Scherzinger has vowed that she would dump her beau Lewis Hamilton if he ever betrayed her.

The 30-year-old singer has revealed that she can't stand womanisers.

And even though she loves her Formula 1 boyfriend, she would break off the relationship if she found the racing driver cheating on her.

"We really trust each other but I would draw the line if he cheated," Contactmusic quoted her, as saying.

"Any woman with self-respect and self-worth wouldn''t tolerate that," she added. (ANI)
