50 Cent is quite the business man and always seems to be finding new projects to get involved with. He recently put out a line of FRIGO RevolutionWear underwear, which go for about $100 a pop for the exclusive joints. However, instead of hiring a professional model for the ad campaign for the undies, Fif just decided to take on that role himself. He stripped down to show off the expensive underwear along with giving us a nice view of his abs and cut-up body. Too bad girls can’t wear them because after seeing this, I’m SURE some female fans would make that purchase. Check out Fif’s new ad for his underwear line in the gallery. Fellas– would you drop $100 a pair on these fly undies?!
