Beyonce KnowlesBeyonce Knowles has revealed she was left traumatised after helping younger sister Solange Knowles give birth.

Solange asked the Destiny’s Child star to be in the delivery room while she gave birth to son Daniel in 2004 but Beyonce told The Ellen DeGeneres Show this week that she was reluctant: “I told my sister that. I said, ‘Please don’t have me in the room,’ and she said, ‘You have to - I’m your sister! Stop being so silly.’

“It kind of traumatized me.”

She added that while she’s nervous, she expects she will have a child (”or a couple, maybe”) of her own one day and that husband Jay-Z will make a great dad: “He’s a great guy. He’s a cool guy. He’s patient.”
