Here are a couple of photos that supermodel Bar Refaeli just tweeted this past weekend featuring her uber hot little self having some fun underwater, and more importantly, showing off her bodacious bikini cleavage. Again, underwater. Which makes said bikini cleavage looks like it’s in a zero gravity room. In other words, it looks extra bodacious, and like it’s trying to escape. Totally. Freaking. Awesome. Enjoy!
