Former Girls Aloud singer Nicola Roberts reportedly crashed her £60,000 Porsche into a motorbike, then hurled abuse at its driver.
Motorcyclist Jason Giles, 21, claims the popstar was more concerned with the damage to her car than his well-being, after he landed in the middle of the road.
Roberts allegedly turned left into a no entry road, swerving into Giles and flinging him from his bike.
Giles, a landscape gardener, told The Sun: “She shouted, ‘You [expletive] idiot. What the [expletive] did you do that for? Look what you’ve done to my Porsche!
“’You’ve only got a broken mudguard, do you know how much this will cost?’
“She didn’t seem to care about me. Her only concern was her car.”
Apparently, Giles’s £850 bike was written off after the accident.
He escaped with cuts and bruises.
Roberts reportedly refused to hand over documentation following the crash at first, eventually agreeing when Giles’s girlfriend arrived and persuaded her.
A spokesperson for Roberts has said: ‘Nicola was involved in a traffic incident and passed the details on to her insurance company who have been investigating it.
“The claims that she swore at the other driver are false.”
