Charlie Sheen reportedly has a secret third girlfriend who likes "porn and vodka".

Megan Levant, 26, has been seen coming and going from the mansion the troubled star shares with his two live-in girlfriends, Natalie Kenly and Bree Olson, in recent weeks.

Megan, a regular on the Los Angeles party scene, has told friends she has been involved with the actor for a number of months, but has kept her relationship a secret.

Friends say she is a perfect fit to join former marijuana magazine model Natalie and porn star Bree as one of Charlie's 'goddesses' - his preferred term for his girlfriends.

A pal of Megan's told The Sun newspaper: "Megan is well-known on the club scene - mostly for her filthy antics. She often goes out wearing next to nothing and is not shy about sex.

"She loves porn and is a regular visitor to the Playboy Mansion."

Megan's now deleted twitter profile had stated: "I like porn and vodka. If you feel The Urge to rescue a dog in need of a home - call me."

Bree and Natalie have previously said they would be happy for more girls to join them and Charlie.

Meanwhile, Charlie's third wife, Brooke Mueller, has decided not to make a restraining order - which prevents him from having contact with their two-year-old twin sons Bob and Max - permanent, while they attempt to work out custody arrangements between them.

The temporary restraining order was granted by a judge at the beginning of March, but will reportedly not be renewed after it expires tomorrow (23.03.11).
