Funny how this “exclusive” doesn’t mention one girl by name.

from www.radaronline.com – Charlie Sheen has been partying hard with porn stars in Las Vegas, RadarOnline.com has learned exclusively.

The Two and a Half Men star had a “revolving door” of porn stars in his Las Vegas hotel room, a source close to the situation told RadarOnline.com.

“Charlie is partying hard. This looks like New York all over again,” the source said, alluding to Sheen’s infamous night with adult star Capri Anderson late last year. That night ended with cops called to Sheen’s hotel room and the star taken to a local hospital after going bonkers.

This time cops have not made an appearance but all of the other elements are there!

“Charlie went there specifically to see the porn stars he stays in touch with,” said the source. The Adult Entertainment Expo was held this past weekend in Las Vegas.

“Sheen didn’t do a meet-and-greet, that’s for sure,” the source laughed. “But he was with a lot of the porn stars in his room and he’s out of control again.”

Writes www.tmz.com – Forget “Two and a Half Men” — TMZ has learned Charlie Sheen has hooked up with 3 whole porn stars in Las Vegas — all at the same time … during what we’re being told is an epic bender.

We’ve learned Charlie hooked up with the 3 women — who are in Vegas for a porn convention.

The foursome are holed up at The Palms Hotel and Casino.

As TMZ first reported, Sheen was seen today hammering down Grey Goose Vodka in the hotel bar.
