Sharon Osbourne has vowed never to host a talk show again, because the structure of daytime TV programmes is too restrictive. The 54-year-old has had two attempts as a talk show host, but both the U.S. and U.K. versions of The Sharon Osbourne Show ended in failure. And she admits the whole experience was a disaster waiting to happen. In her forthcoming autobiography Survivor, she writes, "My ITV (British channel) chat show was a gigantic mistake. I'd had a hard lesson when I did a chat show in America but I hadn't learnt. It was my ego getting the better of me, thinking I could be queen of daytime TV. Wrong! "I had to be so careful what I said and how I said it. No swearing, nothing too provocative. I couldn't be confrontational or probing - two things I might claim to be good at. The questions I wanted to ask, I couldn't. "The truth is, daytime TV is not for me. I just don't fit it. I know that now."
