The 2011 Adult Video News (AVN) Adult Entertainment Expo (AEE) begins today in Las Vegas and runs through the weekend. It’s the biggest gathering of porn stars, studios and insiders. Probably the biggest and best part of the expo will be the 28th Annual AVN Awards ceremony set to take place Saturday night. It’s about 1 billion times better than the Oscars. For one, the dresses these chicks wear are off the friggin’ reservation – that is, when they’re actually in them. These chicks seriously HATE clothes. Even though you’ve probably seen them out of said dresses, here’s a bevvy of big, beautiful lady bumps you’d see at the expo and awards.
