The 33-year-old actor, who will reportedly earn $1million an episode, said that he 'couldn't be more excited' about his new job.
He told Us Magazine, 'I've never probably in my 13 years in show business received more phone calls and e-mails from people congratulating me on this job.
'You'd almost think I won the lottery or something, which I kind of did. I've got the best job in show business, and I am ecstatic about that.'
His new co-star, Jon Cryer, said while he is looking forward to working with Kutcher, he does have one complaint.
'I'm incredibly happy they're bringing Ashton to the show, but the question that I have to ask is, 'Did you have to get the tall guy? Really? Is that necessary?'' he joked. 'But I brought myself to a place of incredible excitement about our new beginning, which I refer to as One And Two Half Men.'
