TV STAR Paul O’Grady will today don a light-up bra and join 15,000 celebrity women and men for a midnight power walk.

The chat show host, who used to dress up as outrageous drag act Lily Savage, is taking part in the Playtex MoonWalk for breast cancer causes.

Birkenhead-born Paul said: “If you’re going to wear a bra, you might as well do it properly.

“It lights up like Blackpool illuminations, Lily would be in her element.

“I’ve had friends who have had breast cancer, cancer seems to touch everybody these days.”

The comedian, who hosts The Paul O'Grady Show, will be pounding the streets of London for a second time.

He said: “I want to raise the profile of the event and help breast cancer causes.

“The atmosphere was fabulous last year.”

Paul will march up to a marathon distance with friends, plus radio DJ Sara Cox and Strictly Come Dancing stars.

Cash will go to Walk the Walk who support breast cancer causes.

Last year, the event raised more than £6m for the grant making health charity.

Nina Barough, the founder of the charity, said: “For fun, this year’s theme is Strictly Walking so we are expecting the glitz, the glamour and the sequins of the ballroom to be transported to the streets of London.

“The Playtex MoonWalk has continually grown over the years, and we want to generate as much support and encouragement for the walkers as possible.

“Walk the Walk is not just about walking, it’s about life, and we hope to make history once again in 2009 by raising more money than ever before.”
