British singer Natasha Bedingfield made a security man's day last year (06), when she ran through a set of sprinklers in her underwear.

She reveals, "At one point, we were outside a radio station and it was really hot, so my PA, guitarist and I stripped off and went running through grass sprinklers. "But we got caught on CCTV."
