Sir Elton John thinks he'd end up in prison if he joined twitter.

The 65-year-old singer refuses to sign up to the social networking site as he knows he would get into trouble almost straight away.

He said: ''It would end my career. I'd be in prison after about two days. I mean, no, God almighty. Me and my big mouth, no thank you. That would be the end of the career.''

Even if he did decide to join twitter, Elton - who has an 18-month-old son, Zachary, with husband David Furnish - admits he would find it difficult because he struggles with the latest technology.

He told The Sun newspaper: ''You won't see me doing a disco record or a dance record or anything like that, because I don't know how. I'm technically a Luddite. I have an iPad but I don't have a phone. I'm not great on a computer, I don't even have one.

''I write everything down - I come from a different era. I accept the change and I know that it is the future with the way it's going, but I don't know how to do it.''
