London, Oct 1 American actress Amanda Seyfried has revealed the horrifying time she had when she tripped and fell down the stairs while performing at the Oscars.

Seyfried, 23, who teamed up with co-star and boyfriend Dominic Cooper to sing the movie's theme tune at this year's Academy Awards, had performed the routine perfectly during rehearsals.

The actress was confident that she and Cooper would impress the star-studded crowd after a perfect practice, but her heel got caught in her outfit, and she stumbled over during the routine.

"The evening before the ceremony, we rehearsed all night and at the dress rehearsal on the day, we nailed it. But during the actual Oscars show, it was a disaster," the Daily Express quoted her as having told Britain's InStyle magazine.

"I fell down the stairs! Just as well Dominic was holding my hand or I'd have been on my a**. Then my heel got caught in my fishnets during one of the really important turns," she revealed. (ANI)
