Campbell scared of catwalk

Veteran supermodel Naomi Campbell is still terrified every time she steps on the catwalk - despite having walked down the runway for 21 years.

Campbell admits she feels insecure whenever she steps onto the catwalk and hopes she can do whatever outfit she is wearing justice.

She says: "When I'm out there, I'm a nervous wreck.

"Still, 21 years later I'm extremely nervous. The day I lose my nervousness I think I have to stop because the nervousness helps me - it pushes me to do my best.

"I think, my God, I've got to show this, got to do this, I'm there to work for the designers. I'm not there to show myself. I'm there to show the product."

Campbell famously tripped on the catwalk in eight inch (20.3 centimetres) Vivienne Westwood heels in 1993.
