from www.tmz.com – Charlie Sheen is with three porn stars in Las Vegas, but not all of them are created equal. His #1 companion is Bree Olson.

Olson is 23 years old, and in 2008 won Best Anal Sex Scene at the AVN Awards.

Olson has range — she was also a nanny on “Keeping Up with the Kardashians.”

Olson is 118 lbs, 34-28-24, and her favorite musical artist is The Carpenters.

As for the types of men she likes, according to her website (which is totally NSFW), she leans toward older guys.

Olson went to college for a year, majoring in Biology.
