I never get tired of seeing Britney Spears in a bikini. Oh wait, yes I do. That's why out of her three bikini appearances this week, I only posted one. But whatever. Sometimes, Britney Spears in a bikini is just inescapable. Like this video of Britney doing the Top 10 on The Late Show with David Letterman. Yeah. I haven't watched it. And really, I'm not going to, but feel free.
