Beyonce Knowles "isn't ready" to have children.
The 'Dreamgirls' star - who married Jay-Z earlier this year - admits she doesn't feel mature enough to start her own family yet.
Beyonce, 27, said: "I know I want kids but I have never been a girl who sees a baby and goes, 'Oh! I want one!' But when I do eventually have a child, I can only pray he is as amazing as my nephew Jules. He's just the best. He is also a lot of work!
"I've seen the reality of having a kid and I know I'm not quite ready for it yet."
The singer also revealed being present when her sister Solange gave birth "traumatised" her.
She added: "I have a nephew, my sister's son and I was there in the delivery room when he was born.
"I had begged my sister, 'Please don't make me because it's going to traumatise me'. But she talked me into it - and I was right! I'm scared of that! I mean, it was amazing and I cried when he was born but it's hard."
