Ashton Kutcher has described his new role replacing Charlie Sheen in 'Two and a Half Men' as "the best job in show business".

The actor, who will replace Sheen on the show from the next season, says he can't wait to get started on production.

He told reporters during the CBS upfront presentation in New York on Wednesday: "In my 13 years in show business, I've never received more emails and phone calls from people congratulating me for this job.

"You almost think I've won the lotto… which I kind of did. I got the best job in show business and I'm excited about that."

Following the news of Kutcher's casting in the show, Sheen claimed the series would fail without him, although he later said Kutcher was the "right guy" to replace him.
