The Rock Of Ages star attended the InStyle magazine bash at the Beverly Hilton Hotel in Los Angeles on Sunday (13Jan13) in a full-length silk dress with a plunging neckline and train.
However, the gown was left in tatters by the end of the night and Hough took to her Twitter.com page to share snaps of two great rips which left her thighs exposed.
The former professional dancer writes, "Ummm I think I may have danced too hard.... Eeek!!!!... I love to dance regardless of how expensive a dress may be... You can't hold me down!!!"
