As proud parents to four children already, Jamie and Jools Oliver were no doubt thrilled to welcome a new arrival into the family.

The celebrity chef couldn't help but gush about the exciting news on Instagram, where his prowess in the kitchen showed through as he revealed the little one weighed the equivalent of "16 packs of butter".
He wrote on the site: "And then this just happened guys !! IT'S A BABY BOY !! Everyone in the Oliver family is very surprised and beyond happy ...
"8 lbs ( that's 16 packs of butter for you bakers out there) anyway were all hitting the hay it's been a long day big love... bless a little baby boy Woop Woop !!!! And love to all you mums out there how amazing you are it blows my mind .... Big love jamie o p.s no baby names yet (sic)."
And it was a family affair as the 41-year-old star was joined in the delivery room by his two eldest daughters Poppy Honey Rosie, 14, and Daisy Boo Pamela, 12, towards the end. Having three of his favourite ladies with him at the time left him feeling "very very emotional".
He added in his post on social media: "He arrived safely, mum / @joolsoliver was really really amazing, unbelievably composed, natural birth and my two eldest Girls got to come in at the very end as the baby was born which was amazing to witness very very emotional. (sic)"
The couple also have Petal Blossom Rainbow, six, and five-year-old son Buddy Bear Maurice together.
