Actor Charlie Sheen has prompted speculation that his sitcom Two And A Half Men may end after releasing a statement about his role on the show.

The star made his remarks after reports in the US press that he was demanding a pay rise to continue his role as Charlie Harper in the show, which is the highest rated sitcom in the States.

Reports suggested he was asking for $1m an episode before he would agree to commit to an eighth series. He is thought to currently earn around $825,000 per episode.

However in a statement released to People Magazine on Friday, Sheen said the reports were “false”.

“Claims from ‘inside sources’ regarding offers from the studio as well as my salary, on their best day, are without merit,” the star added.

The statement was released on the last day of filming for the current series of the show – but Sheen denied that by doing so he was making a last-ditch attempt to secure more money.

“Approaching the start of the current season and as far back as June 2009, I submitted my terms for season eight to Warner Bros. and CBS respectfully.

“In no way, has this been a hasty or negligent 11th hour surprise.”

However he also indicated that he was willing to quit the show altogether. If tonight’s show is the end for me as Charlie Harper, so be it. Another journey has begun,” the statement said.

“I take from the experience 161 shows filled with a kaleidoscope of amazing experiences, memories, friendships and gratitude. I remain humbly inspired – C Sheen.”

Warner Bros and US network CBS, who make the show, did not comment.
