Karina Smirnoff and Ralph MacchioA new week means a new fall on 'Dancing with the Stars'.

But this time Kirstie Alley was nowhere near the incident. In fact, it was front-runner Ralph Macchio's professional partner Karina Smirnoff who fell and fell hard, but it looked more like a wardrobe incident than a dancing error.

Macchio was sporting a long jacket with a flared bottom that cascaded across the floor when he got low, and it was this excess portion of his jacket that knocked Smirnoff off her feet.

To their credit, Macchio quickly helped her back to her feet and they regained their composure and continued the performance.
