Here are a whole bunch of screaming hot new Armani Underwear advertisements featuring a blond haired and scantily-clad… Rihanna!? Holy hell, I thought this was Megan Fox’s gig!? WTF!?!? Well, first let’s just calm down, and second, let’s just pretend that Megan is taking a very short sabbatical, and that Rihanna is just stepping in for the meantime, so we can all enjoy these sexy photos instead of resent them. Seriously though, Rihanna looks wickedly sexy in these shots, and it’s partly due to her funky blond hairdo… but mostly due to her shwingtastic cleavage, legs, and killer curves in sexy underwear. Enjoy!
