Charlie Sheen's Porn Star Party Pal: Porcelain Teeth, Three-Minute Sex and Other Binge Night Shockers

According to Kacey Jordan, Charlie Sheen checked into rehab not a moment too soon.

"He said, 'I bet I can outdrink you,'" Jordan tells E! News in an exclusive interview airing Monday, describing her first impression of Sheen during an alleged 36-hour party binge that led up to his hospitalization Thursday morning.

Jordan says that she witnessed Sheen drinking and smoking cocaine for hours, after which they had "quick" sex and he cut her a check for $30,000. Which she immediately deposited, despite the fact, she said, that she had reservations about leaving him alone. Sounds like pretty risqué behavior, but Sheen is wondering what the fuss is all about. "I'm fine," he wrote in a text to RadarOnline, according to the site. "People don't seem to get it.... Guy can't have a great time and do his job also?"

Hold that thought.

Jordan, who describes Sheen as "a very nice and polite guy," tells E! that he for the most part acted "normal" even while high because, in her opinion, he's so used to being in that state. The adult-film actress also says Sheen told her he has "porcelain teeth" after drug use caused too much wear and tear on his real teeth.

Sheen told Jordan, she says, that, with her blonde hair, she was "the missing puzzle piece" of the "porn family" he was looking to move into a $20 million home. He added that there were other women at his house when she first arrived, but that he was so enamored with her, the others eventually took off in a jealous huff.

At around 3 a.m. on Thursday, Jordan says, one of the other, er, ladies sideswiped his parked car while attempting to leave the house, sending Sheen into a fit she thought would turn into "another Plaza Hotel," referring to the night Sheen was hospitalized in New York after an alleged freakout in his hotel room that his rep initially classified as a severe allergic reaction.

"He was punching walls" and "yelling in outrage" at 3 a.m., Jordan says, until the other driver calmed him down.

Jordan says that she immediately left to cash the $30,000 check Sheen had given her, though she claims she was afraid to leave him alone, fearing it would be the last time she ever saw him alive.
