Here’s a photo that Rihanna just tweeted of herself in a tiny bikini while on vacation, and I’m guessing that she did so because she knows how ridiculously hot she looks in a tiny bikini, and especially how insanely sexy her bodacious booty looks in a tiny bikini, and how badly we want to see all of those things. And drool over them. Hell, even her shadow looks freaking hot. Especially when you realize the pose she’s busting out. Thanks Rihanna! Keep it up!
