Just when we thought we'd seen most of Danica Patrick in a GoDaddy commercial, here comes this revelation ...

The NASCAR Sprint Cup racer has traded in her fire suit for a muscle suit.

Pictures of one of two GoDaddy Super Bowl spots for 2014 have surfaced and they show Danica as an incredibly believable musclehead. Don't think so?

That sports bra and running shorts is the most clothing Danica has worn on Super Bowl spots of late. In previous editions she's been seen unzipping a leather jacket, taking a shower and wearing nothing more than high heels.

Here's a bit of trivia you can share with friends on Feb. 2 when the spot debuts: Danica's 2014 spot will be her 13th appearance in a Super Bowl commercial - that's more than any other celebrity.

Check out this video of the shoot:
