LILY ALLEN was terrified she would be left paralysed after taking a nasty tumble during her recent world tour.

The Smile hitmaker fell over last month (Aug09) while enjoying a night out with friends mid-way through her European jaunt.

As she tried to walk off the injury, she realised it was much more serious than she first thought, as she couldn’t stand up.

The pain was so intense she feared the worst – and even worried her legs would need to be amputated.

She says, “It was really the most painful thing ever. It was really horrible. I had one of my security guys with me, and he said he turned around and just saw these two feet sticking into the air.

“You know when you fall over your natural reaction is to get straight back up again? But I was in so much pain I thought I was paralysed or something. I mean, I really thought that I was going to have to have my legs cut off.”

The star fought through the injury after a painkilling injection and forced herself onstage in Finland the following night (16Aug09) – only to break down in tears in front of thousands of fans.
