Blue Peter's Helen Skelton has completed her incredible high wire challenge for Comic Relief!
She managed to walk the 150 metre long stretch of tightrope a massive 66 metres up in the air in just 11 minutes.
She braved the wind and the drizzle as she walked on a wire the width of a one penny coin between two chimneys at London's Battersea Power Station.
Not only did she have to concentrate on staying on the wire, she also had to carry an eight metre long balancing pole!
Helen has two new records to add to her Amazon challenge last year. She's the first person to ever walk on a tightrope between the building's two chimneys...
It's also the highest-ever high wire walk by a female in the UK. Well done Helen!
The 27-year-old Blue Peter presenter said that after her training in France she had never had so many bruises in her life!
