London - (Helter Skelter): A mystery bidder upped the stakes this weekend in Helen Skelton's high wire bid between Battersea Power Station's chimneys.
The children's show presenter is being tempted with a whopping £250,000 to get her kit off for her March 18 fundraiser stunt.
High wire novice Skelton, 27, only began training last October for the Comic Relief heart-stopper.
She's signed up to walk the 492ft length between two of Battersea's disused chimneys - without a safety net below the 216ft drop.
"I'd been planning to wear a standard issue thermal suit and trainers," the blond anchorwoman commented, "when the £250K email to the Beeb literally knocked my socks off.
"I'd say yes like a shot if the filming was to be in, say, June. Unfortunately the 28 February date virtually guarantees I'd freeze my nipples off in the unforgiving London cold."
The BBC is keeping the bidder's ID secret despite wild rumors claiming it's a Canary Wharf bank, appeasing recent bonus furor negative publicity.
Online spreadbetting agents Aintgottaprayer.con offer 5/4 on Skelton pulling out before the big day.
