(Cover) - EN Showbiz - Charlie Sheen is 85% sure hell return to Two and a Half Men.

The troubled star was sacked from the American television show after he made a number of unflattering comments about producer Chuck Lorre, network CBS and production company Warner Bros. Charlie was angry production of the programme was halted while he received rehab treatment at home, and later that he wasnt allowed to return to filming when he thought he was well enough.

The star is currently completing his US comedy tour My Violent Torpedo of Truth / Defeat is Not an Option, which took him to Boston this week. While there he gave an interview to a local radio station, where he claimed he may reprise his role as Charlie Harper on the show.

Im 85% sure, he replied, when asked if hed return. Oh God yeah. Theres been discussions but I was asked not to divulge anything.

The star famously launched a multi-million lawsuit against Lorre and CBS, and explained his reasons for doing so while at the 98.5 Sports Hub studios. He claims he is receiving no money for episodes being aired which star him.

They can't [justify withholding payment], that's why I'm suing them, he said.

Sheens comedy tour has had mixed reviews. In some areas he has bombed, with the crowd booing him off stage and walking out before it has ended. He was asked how he copes with that, and said the key is to not let it get to him.

You just sort of power through it and try to get through as much of it as you can with as much positive energy as you can and as much hatred as you can, he said.

The 45-year-old has repeatedly hinted he would like to return to Two and a Half Men during his live shows, but has stopped short of offering Lorre a full apology.

It is unknown how much the tour has netted Sheen, although it has been revealed he is making $750 a time by inviting audience members backstage to meet him for just two minutes. (C) Cover Media
