Jamie Oliver's wife Jools has given birth to a baby boy.

The TV chef - who already has three daughters Poppy Honey, eight, Daisy Boo, seven, and 17-month-old Blossom Rainbow with his 35-year-old spouse - announced the birth of their son Buddy on his twitter page yesterday (15.09.10), just hours after his arrival.

He wrote: "It's a baby boy guys !!! I'm shock, were all very happy, mum was amazing and both are well and happy x4 kids!! What a day. now i have to pretend to know about football!! all tips on boys excepted much love jamie oxx (sic)?!"

The 35-year-old chef then added in another post on the micro blogging site: "Mr Buddy Oliver .....full name to come from mum....big love joxx (sic)"

The cookbook author has never kept his wish for a son quiet and previously admitted he would consider adopting a baby boy to level out his "oestrogen-filled house".

He said: "If I can't produce a boy I will have to adopt one. I would consider it. We have three beautiful, healthy girls and we cherish them. But I'd be lying if I said it wouldn't be great to have a boy. Adoption is such a selfless act and they have a lovely family environment. It's humbling and beautiful to see.

"Jools would like to have another child but there are so many vulnerable orphans out there. Jools and I need to sit down and have a very serious conversation about it."

Jools - who suffers from polycystic ovaries - fell pregnant with the couple's eldest daughter Poppy after a series of In Vitro Fertilisation (IVF) but is believed to have had the last three naturally.
