Nicole Scherzinger tried to jump out of a moving limo, it has been reported.

The 'Your Love' singer is said to have caused a rush-hour crash when she leaped out of the back seat of her driver's car after shouting that she was feeling sick and ordering him to pull over.

A source told The Sun newspaper: ''She was in the car back to her hotel at 7pm when she started to feel ill.

''She screamed at the driver to pull over, but it was impossible to stop. She must have been really disorientated because all of a sudden she opened the door.''

The driver had refused to bring the car to a halt because of the busy traffic but was forced to slam on the breaks when the 36-year-old star jumped out.

However, in his rush to get to the side of queasy Nicole, he left the car in gear causing it to lurch forward and crash into the rear end of another vehicle on the busy carriageway.

Nicole - who is dating Formula 1 driver Lewis Hamilton - had been filming the music video for her new single 'Run' on Victoria Embankment in London.
