Rihanna is already a member of SCWDAWP (Sexy Celebrities Who Don’t Always Wear Pants). In fact, she’s the group’s third most powerful member, behind only Lady Gaga and Ke$ha in importance. And when you’re one of the best, you can’t let people forget. That’s why this weekend, while in London, Rihanna went pants-less again and reminded us why we enjoy this trend of celebs not wearing pants so very much. Mainly it’s because it gives us a chance to see celebrities not wearing pants. That was pretty obvious, wasn’t it?
