She’s already known for her rock-hard bod and iron will. Now, “Biggest Loser” coach Jillian Michaels is turning full-fledged superhero, and we’re taking you behind the scenes!

In her new “Go Daddy” Super Bowl commercial with racecar star Danica Patrick, Jillian dons a cape and shiny, form-fitting costume to become a “Super ‘Go Daddy'” girl.

The fitness guru tells ET she “jumped at the chance” to be in the commercial because Go Daddy “takes strong women that excel in male-dominated sports and they celebrate that and they allow you to be powerful and successful.”

“And they’re all about being sexy and edgy and fun, and those are traits that I feel represent my personality,” adds Danica.

Super Bowl XLV kicks off Sunday, Feb. 6.
