Demi Lovato Knocks Down Rocky Star Sylvester Stallone

(Radio.com) Demi Lovato showed off her fighting skills on Wednesday (Nov. 3) when she strapped on some boxing gloves and got into the ring with Rocky star Sylvester Stallone.

The two superstars danced around the mat at the Unbreakable gym on Sunset Strip, all in good fun. At one point, the 70-year-old swung and Lovato ducked the punch, then delivered a blow that sent him to the mat.

Stallone popped back up and said, "I slipped, I slipped, I swear it was an accident!" TMZ caught the whole thing on tape, so it must not have been any sort of publicity stunt. Read more here.
