Portions of the interview will also air on 'Good Morning America' on Monday and Tuesday. According to The Hollywood Reporter, ABC plans to promote the interview during the Oscars telecast Monday night.

Canning visited Sheen and his two female companions at his home over the weekend for the interview, where he told her, 'I am on a drug. It's called Charlie Sheen.'

'Two and a Half Men' went on hiatus last month after Sheen entered an at-home rehab program following reported partying and a trip to the hospital for abdominal pain. CBS and Warner Bros. halted production for the rest of the show's season on Thursday, citing the 'totality of Charlie Sheen's statements, conduct and condition' in a joint statement.

Sheen told Canning he is 100 percent clean and plans to show up for work despite the show's shutdown."
