Joan Rivers, GoDaddy's New Spokesperson, Stars In Super Bowl Ad (VIDEO) revealed its newest spokesperson in a 30-second Super Bowl ad.

The commercial features current GoDaddy spokeswomen Jillian Michaels and Danica Patrick introducing the mystery woman, "a hot Hollywood icon," who turns out to be none other than veteran comedienne Joan Rivers.

Rivers, 77, looks surprisingly youthful in leather shorts and a black tank top. "Is it hot in here, or is it just me?" she shouts. The audience in the ad reacts with shock.

Rivers, who has joked about her various plastic surgeries, tweeted the following after the ad debuted: "Yes, yes, yes, it's my body in the @GoDaddy ad." The truth, however, is that Rivers agreed to use another GoDaddy girl as a body double for the commercial, according to CBS News. Her head appears atop the shoulders of Tabitha Taylor, who appeared in a 2009 GoDaddy Super Bowl ad.
