Britney's all man

She was the world's most famous virgin, who proclaimed she did not believe in premarital sex.

Until, that is, Britney Spears finally admitted she had done the deed with boyfriend Justin Timberlake.

However, she did not give in easily. Yesterday, the singer revealed she kept Timberlake waiting for three years before they did 'the thing'.

But she insists that having sex did not make her a 'bad person'.

The pair, who worked together as child stars, dated for several years.

Spears said she was the one wearing the trousers. The 21-year-old added: 'I've always been a tomboy, I've always ended up being the man in the relationship.

'I know it sounds really weird but it's very hard for me to let go and let the man take control.'

She had believed the former *NSync star, nicknamed Justin Trousersnake, would become her husband.

'As far as the whole sex thing goes, I really did think Justin was the one I was going to marry so I did do the thing with him after three years,' she added.

'I don't think that's a bad thing. Just because I've admitted to having sex doesn't make me a bad person, does it?'

The Baby One More Time star has shed her innocent image and recently enjoyed a fling with heavily tattooed limpbizkit hardman Fred Durst.

But she revealed she would not go to bed with a man early in a relationship.

'I think it's more sacred and special if you just kiss,' she told GQ magazine.
