Lily Allen thought she would have to have "her legs cut off" after falling on her coccyx.

The 'Fear' singer cried throughout a concert in Helsinki, Finland, last month, because she was in so much pain after tripping over during an evening out.

The 24-year-old star said: "It really was the most painful thing ever. It was really horrible, because I had one of my security guys with me, and he said he turned around and just saw these two feet sticking out of the floor, in 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."

Lily fell while watching two DJ friends working. She was "crouching" behind the decks so other partygoers wouldn't see she was there when she slipped and fell backwards off the stage.

She explained to Absolute Radio's Geoff Lloyd: "They basically gave me what I can describe as like an epidural, and yes, it numbed from my knees to my lower back to get through this show.

"But then half-way through the performance the thing started running out and I just burst into tears on stage. It was so horrible. I was sobbing real toddler tears."
