Megan Fox's Armani Code Sport Commercial

Welcome to "no pain, no gain," Megan Fox style.

For her latest Giorgio Armani campaign, the brunette bombshell—sporting a black bobbed wig and not much else—is seen rewarding her hunky love interest after his midnight swim with a sexy embrace underneath her black towel. Beats Gatorade!

The just-released TV commercial for the Armani Code Sport fragrance kicks off with a nude, tattooed Fox awakening. After a few sensual shots of the actress between the sheets, she sets off to find her man (played by male model Chris Folz), who is seen doing laps in a rooftop pool ... not to mention a tiny pair of briefs.

With an ad this smokin', the fragrance could smell like chlorine and it would still fly off the shelves. Good work, team.
