Katherine Jenkins suffered a back injury while performing on Monday's "Dancing With The Stars" semifinals It was during the Welsh classical singer's second competition number - at the tail end of her salsa with  pro dancing partner Mark Ballas  that she was injured.Mark spun Katherine around, she did a backbend, and as he was stepping over her, she seemed to stumble and fell to the ground. Katherine got up and tried to finish the number, but fans could see her wincing.

The pair received consecutive 9s from the judges, for a total of 27. It was their lowest score of the night.

Maria Menounos and her partner Dereck Hough took the  top spot on the leaderboard.
