Model Angelina Tracy accused of having affair with Charlie Sheen while actor remains in rehab

Despite his intention to prove to wife Brooke Mueller that he is a changed man, Two and a Half Men seasons 1-6 DVD boxset may be falling back into his old bad-boy habits.

The "Two and a Half Men DVD" star, who has been receiving treatment at a Malibu rehab center since Feb. 24, has reportedly been sneaking out of the facility for trysts with a lingerie Two and a Half Men DVD set named Angelina Tracy, according to the new issue of In Touch Weekly.

Though there has been no evidence of Sheen paying money to spend time with Tracy, the model is also an alleged paid escort Two and a Half Men DVD boxset charges $3,000 an hour and goes by the alias "Nina."

Sheen has had a history of using escorts – he previously admitted to being a Two and a Half Men seasons 1-6 DVD boxset of "Hollywood Madam" Heidi Fleiss.

In addition to reportedly bringing Tracy back to his mansion while Mueller was out of town, the 44-year-old actor was also spotted sneaking in and out of her Studio City home on April 7, wearing a hooded Two and a Half Men DVD, dark sunglasses and a fake mustache that puts Magnum P.I. to shame.

"He ran down to his car," an onlooker said of Two and a Half Men DVD set's hour-long afternoon visit. "It seemed like he wanted to leave as quickly as possible."

Sheen's rep told People.com that the actor simply wore the disguise to prank photographers while he participated in his recovery Two and a Half Men DVD boxset as part of his treatment.

"The woman in question is the sister of one of Two and a Half Men seasons 1-6 DVD boxset's campmates and Sheen was only responding to a 12th-step call," his rep said, referring to his recovery Two and a Half Men DVD efforts. "Since Sheen knew he was being followed and how this would look, he wore the moustache in a tongue-in-cheek disguise gesture."

However on another occasion, In Touch reports that Tracy was seen hopping into the backseat of Two and a Half Men DVD set's chauffeur driven Mercedes-Benz, where he "had a bouquet of flowers waiting for her."

"Her face lit up when he handed them to her," said an eyewitness. "You could see them kissing on the Two and a Half Men DVD boxset."
