Move over, Kim Kardashian. Rihanna just stole the show in the butt-baring department. Just days after photos surfaced of Kim K on a beach in Thailand showing off almost her whole entire butt, RiRi showed her who's boss when she went full-moon in the Hollywood Hills.
Both girls were doing some sort of photo shoot, which is crazy when you think about it. That's "work" for them. And it's work for the guy taking the photos, and the guy who brushed the sand onto Kim's butt. Beats the hell out of sitting in a cubicle, that's for sure.
Obviously, with both girls showing an unprecedented amount of a**, we can't help but wonder whose butt is better. Truthfully, Rihanna has been so busy posting half-naked frontal photos, we never even realized she has such a beautiful butt. Then, there is Kim's, which already has a built-in fanbase.
For the moment, we'd have to vote Kim's "Most Popular" and considering what gravity might do to Kim's in 20 years vs. what it will do to RiRi's, we're gonna vote hers "Most Likely to Succeed."
