Ellen DeGeneres has revealed that she cannot envisage a career beyond her US chatshow. The openly lesbian comedienne rose to fame as her character came out in her '90's sitcom Ellen, but now she says she has no plans to return to acting. She told Entertainment Weekly: "I'm going to be doing this for a long time, so I can't imagine wanting to do something after. The talkshow is pretty much going to be it. When I walk away from this, I'll walk away for good." However, the 50-year-old said she was unsure exactly how long she would stick with the series, which has been on the air since 2003. She said: "Ten more years is a long time. I could be hovering in a space suit because we should be flying by then. We were supposed to fly a long time ago, according to The Jetsons. "The audience wouldn't even be seated in chairs, they'd be in some type of swinging harness and we wouldn't be talking. Instead of applauding and cheering, it'll change to hums, like dolphins. So I'll hum in a certain way to say goodbye. That's probably how I'll sign off." DeGeneres was recently voted the US's favourite television personality, beating last year's winner Oprah Winfrey.
