Brook felt "self-conscious" in 'Playboy'

Kelly Brook has admitted that she felt "self-conscious" during her recent Playboy shoot.

The 30-year-old, who posed for the publication with just a bow tie, bowler hat and umbrella, said that she was slightly intimidated by the appearance of the other models in the magazine.

In her September issue, she said: "I was a little self-conscious about the shoot because I look at the other girls in the magazine and they're just so perfect. I'm not 20 anymore - my boobs are real, and they even hang a little."

The Piranha 3D actress also complimented photographer Ellen von Unwerth, who shot the upcoming set.

"Ellen is amazing," Brook added. "She really brought us back to those gorgeous shoots from the 1960s and '70s, when the girls were all natural. You don't see that very often these days."

Road safety groups recently blasted an advertising campaign involving Brook - in which the model wears nothing but trainers - claiming that the billboards are a distraction to drivers.
