Nascar diva Danica Patrick turned heads on Wednesday-and not for modeling in a bikini (which she's done twice for Sports Illustrated) or even her signature acid green racing togs. The 31-year-old was spotted looking like a massive she-Hulk heading up a Los Angeles foot race in a black sports bra and chartreuse booty shorts. Only last week, the petite brunette got gussied up as a showgirl for the American Country Music awards and joked, "The good thing about me, is that there's no chance of a wardrobe malfunction…there's not much to malfunction!" She added with a wink: "I hope that little bit didn't fall flat." So, what gives with the new body builder look?

No need to call in the doping police to test for illegal enhancing drugs, the world's most successful woman race car driver was actually wearing a hyper-realistic muscle suit complete with a hardcore six-pack, ripped biceps, and bulging veins. Managing to smile despite what appears to about 75 pounds of sweltering, sweaty latex, she was starring in a new commercial by her sponsor GoDaddy, the Internet domain name company, which will air during Super Bowl XLVIII.

Last year, squeezed into a black leather moto jacket and skinny jeans, Patrick appeared in one of the most talked about ads of the game, which gagged millions of viewers by featuring sexpot model Bar Refaeli making out with uber nerd Jesse Heiman. She's appeared in other number of other provocative ads for GoDaddy as well, usually barely dressed and winking at the fact that, for some of her fans, her looks are as important as her driving prowess.

Patrick has managed to straddle the line between sex symbol and superstar in a sport that's as turbocharged as with testosterone as they come. She's done so in part by refusing to see the sexism in her objectification and instead, like the post feminist powerhouse she is, working it to her advantage. In early 2013, she told Yahoo, "People have been pretty cool from the beginning. I didn't grow up in an era where women weren't allowed in the pits or women weren't accepted. I've grown up in an era where people are excited for it."

Meanwhile, the Internet domain name company says Patrick's new ad is part of a move away from leaning on half naked women to sell their product. "The women you'll see in our Super Bowl commercials this year will be super-smart, successful small-business owners," Barb Rechterman, chief marketing officer told USA Today. GoDaddy? Go, Danica!
