Family guy Jamie Oliver has fourth bun in the oven

TV chef Jamie Oliver and his wife Jools are expecting their fourth child, it was announced today.

Model and writer Jools is due to give birth in September and the pair are said to be "delighted".

The couple became parents for the third time less than a year ago when Petal Blossom Rainbow was born in April 2009.

They also have two other daughters with floral themes to their names - Poppy Honey and Daisy Boo.

A statement on behalf of the couple said: "Jamie and Jools Oliver are delighted to announce that they are expecting their fourth child."

The couple celebrate their 10th wedding anniversary this June.

Oliver, 34, has spoken in the past of his desire for a boy in his brood. He has joked how he needs another male in the home as "back-up" when he gets bossed around by the girls.

The couple's first child, Poppy, will be eight this month, while Daisy turns seven in April.

Oliver is estimated to be worth around £40 million through his various restaurants, cookery books, accessories and advertising deals with Sainsbury's.
