Delighted father Jamie Oliver proudly showed off his first son today and said he was "shocked" to have a little boy.
His wife Jools gave birth to Buddy Bear Maurice at 6.10pm yesterday after what she described as a "hard and fast labour".
The celebrity chef said his family was now complete as he stood with his four children and wife outside the Portland Hospital in central London.
Asked how he had chosen his son's name, he pointed to his wife, who shrugged her shoulders and said: "I just like the name Buddy, I thought it was sweet."
He was given the name Maurice after Jools' late father, who died in 1997 after a stroke.
The unusual choice of name is in keeping with family tradition.
Buddy's older sisters are Poppy Honey, eight, Daisy Boo, seven, and 18-month-old Petal Blossom Rainbow.
While the girls appeared delighted with their baby brother, Oliver admitted he was shocked to have had a boy.
Kissing his son on the head, he said: "I never thought for a moment I would have a boy. All you can ever dream of is having a healthy child and that's the best thing in the world.
"In a way it would have been easier to have had a girl. We're not prepared for a boy - there's no blue in the house.
"When I saw the crown jewels it was a big shock. It's really nice to have a boy."
Holding the baby, wrapped in a white blanket, he added: "It's wonderful... I didn't think I had it in me."
Smiling for photographers, he suggested the infant had butcher's hands but admitted he did not know what colour his son's eyes were.
He said: "I think they're brown, I'm not sure yet."
Asked if he hoped the baby would follow in his culinary footsteps, he said: "I don't know. I'm not going to push him into it. My dad didn't push me."
Dressed in jeans and flat ballet pumps, Jools looked happy but exhausted as she stood with her young family.
Asked about her two and a half hour labour, she said: "It was hard and fast but he was great."
Hugging his wife, Oliver added: "She did a great job."
Buddy's parents announced his birth on Twitter, with Oliver declaring: "It's a baby boy guys!!! We're all very happy, mum was amazing and both are well and happy."
The baby, born naturally, weighed in at 6lb 9oz.
The family left hospital at about 3pm.Reuse content
