Bree Olson is the Queen of Charlie Sheen’s Foursome in Las Vegas (Pics)

In a completely shocking event, Charlie Sheen is reported involved in another bender. This time he was spotted partying with three porn stars at the Palms Hotel and Casino is Las Vegas. Since the girls were all in town for the AVN Porn Convention, it was inevitable that Sheen ended up in a foursome.

The lead girl of the group is reportedly Bree Olsen, who was even more recently reported as making out with the cause of the Jesse James/Sandra Bullock break-up… Michelle “Bombshell ” McGee. We reported back in October that Bree had won the “World’s Biggest Whore” Pageant on the Howard Stern show. At least she is wearing her crown with pride.

During that Stern appearance, Bree said that she sometimes posts on Twitter that she’s horny and just waits for random guys to come bang her. She felt like such a whore one time, she tracked down her building’s janitor and begged him for sex until he relented. Maybe you guys should follow her tweets.

Apparently Sheen was just a tad bit late for his set call for Two and a Half Men Tuesday morning… but not by much. He reportedly flew in by private jet and showed no signs of being affected by a drug and alcohol-induced weekend of banging pornstars. His constitution is stuff of legend.
