WATCH: Sailor Brinkley-Cook impresses on 'DWTS' as fill-in for Mom Christie

Another season of Dancing with the Stars is underway, and it started with some bad news. The cast needed an injury replacement.

Supermodel Christie Brinkley broke her arm in rehearsals, so she could not be a part of the show. But, her daughter Sailor Brinkley-Cook filled in.

The injury occured five days ago during the rehearsals, and the younger Brinkley not only stepped up to fill her mother's shoes, she had everyone talking about her performance.

You can watch her performance, and what happened to Christie, below. You can also read more about it HERE.
