The mystery woman who locked herself naked in a Plaza hotel bathroom during bad-boy actor Charlie Sheen’s coke-fueled frenzy was identified as a smokin’ hot porn star from New York City.

Erotic actress Capri Anderson has told friends that she was “extremely afraid” of Sheen and that she called Plaza security during his rampage because she felt “threatened” by him, TMZ.com reported.

The 22-year-old Anderson — who fled the scene after the slimy and sloshed Sheen was hospitalized Tuesday because of his meltdown — angrily denied the assertion by law-enforcement sources that she’s a hooker.

Anderson “is adamant she’s NOT a working girl,” reported TMZ.

But she did go back with Sheen to the “Two and a Half Men” star’s room that night up in The Plaza — as his two young daughters and their actress mom Denise Richards slept in rooms across the hall.

The petite porn princess, who also “acts” under the nom de cinema Alexis Capri, has appeared in such video gems as “Virgins of the Screen 6,” “Cable Guy Sex” and “Filthy’s First Taste 7.”

Her Facebook page’s bio indicates that her real name is Christina Walsh — the name she gave cops Tuesday morning.

The bio, which says she resides in Argentina, said she left her family at age 18 to pursue her career because they did not want her to pose nude for pictures.

Asked which sex she’s interested in, she lists: “Women.”

Sheen, 45, has a well-known, long-standing penchant for both porn stars and prostitutes, having admittedly dated blue-movie legend Ginger Lynn and dropped big bucks on escorts from the stable of Hollywood Madam Heidi Fleiss.

So it would come as no surprise that he hit it off with Anderson, whom TMZ said met Sheen for the first time Monday in the Plaza’s bar and then agreed to join him, four other gals and three other guys at the nearby restaurant Daniel’s.

Richards, who was in New York with her family to promote her new role on the show “Blue Mountain State,” also joined the group for dinner — but ducked out before even finishing her appetizer when her boozed-up, ex-husband Sheen began acting out.

Sheen later invited his new beautiful friend Anderson back to his 18th floor room at The Plaza — where things quickly got ugly.

Cops responded after security there phoned 911 at 1:33 a.m. Tuesday and reported a dispute in room 1831, where Sheen was staying.

When police officers got up to the room, they found Sheen naked and “not coherent” and Anderson nude and cowering in the bathroom, where she had taken refuge when Sheen began tossing over tables and chairs and smashing an expensive chandelier.

While hiding in the bathroom, Anderson had desperately phone a friend who was “working” elsewhere in the hotel, a source said.

Sheen, who admitted having drunk booze and done cocaine that night, told cops he “wigged out” after noticing his wallet and cell-phone missing after being in the room with Anderson, sources said.

“[Anderson] said after he did the coke, he flipped out, couldn’t find his wallet and accused her of stealing it,” one source told RadarOnline.com.

No charges were filed against Anderson.

Sheen also was not charged — after he agreed to be taken to New York Hospital, with Richards riding in the ambulance with him — for a psych evaluation.

He checked out hours later, texting a RadarOnline reporter afterward: “Oh my man, I’m fine. The story is totally overblown and overplayed as far as the reality of the scenario.”

Sheen then flew back to Los Angeles, where he is set to resume shooting next week for his CBS sit-com, which pays him nearly $2 million per episode.

Sheen’s spokesman has blamed the actor’s violent antics on an “allergic reaction to medication” — a claim that has met with widespread derision given his client’s long, notorious history of drug and alcohol abuse.

Sheen has agreed to compensate The Plaza for the damage that he caused, which is estimated at more than $7,000.

“The room was a mess,” a hotel staffer told The Post today. “There were sheets everywhere, his clothes everywhere. Even a chair was broken.”

“The room was a disaster. He must have been very angry.”

Colorado prosecutors have said they probably won’t try to have Sheen locked up for violating his probation there for the Christmas Day 2009 assault of his third wife, Brooke Mueller. Sheen has just a week to go on that probation.

Richards, 39, on the “Today” show, said, “The details of what went on in the room, what went on that night, I prefer to keep private and personal.

“My daughters” — Sam, 6, and Lola, 5 — are very unaware of what happened, and I’m really trying to protect them. This is Charlie. If he wants to discuss it, then I’ll let him do it … I don’t want to say anything.”
