Ashton Kutcher has "no idea" about the future of 'Two and a Half Men'.

The 34-year-old actor joined the show as a replacement for Charlie Sheen last year but admitted he hasn't been told yet if the programme will be renewed for a tenth season or if he will even continue to play the role of broken-hearted internet billionaire Walden Schmidt.

He said: "I don't think the show's been picked up for another season yet. I absolutely adore the time that I'm having. I'm having a great time on the show. There's some work I have during summer.

"I haven't heard from the powers that be yet."

Meanwhile, creator Chuck Lorre revealed Charlie is still a part of the show's "DNA" despite his acrimonious exit where he verbally blasted the showrunner.

He said: "It's in our DNA. He's very much a part of our show, part of our lives. We've had wonderful years together and I'm not going to pretend they didn't happen."

If 'Two and a Half Men' is renewed for a tenth season, Chuck has promised big storylines for Jake (played by Angus T. Jones) as he graduates high school.

He said: "There are some milestones coming up at the end of the season for the show, including Angus' character graduating high school. What's next for the young taterhead? We're starting to explore that now because it's a huge transition for this young man; what's going to happen to him afterwards and how terrifying it is for his parents."
