Gay actor Rupert Everett has warned about the dangers of children having sex change operations after revealing he wanted to be a girl when he was young.

The 57-year-old, who explained he always dressed as a girl in his youth, encouraged people to embrace the 'ambivalence' of their gender rather than resort to medical procedures.

He said he would have regretted a sex change.

'I really wanted to be a girl. Thank God the world of now wasn't then, because I'd be on hormones and I'd be a woman. After I was 15 I never wanted to be a woman again,' he told the Sunday Times magazine.

The Musketeers star believes parents who 'get medical' are scary, adding: 'It's nice to be allowed to express yourself, but the hormone thing, very young, is a big step.

'I think a lot of children have an ambivalence when they're very young to what sex they are or what they feel about everyone. And there should be a way of embracing it.'

He also suggested that Caitlyn Jenner, the TV personality who was formerly Olympian Bruce Jenner, had made a mistake in undergoing gender transition and had no clue' in what being a transsexual involves.

The St Trinian's actor also spoke of how former girlfriend Beatrice Dalle, the French actress, thought she may have been pregnant with his child.

Everett told the magazine: 'She and I often talk about what would have happened if we'd both had this child. And I would have loved to have had that child, actually.

'God, it probably would have been in rehab by now.'

He also revealed that he is 'turning into his mother', and plans to move back in with her in Norfolk.
