Jamie Oliver, wife Jools welcome baby No. 5

LONDON, Aug. 10 (UPI) -- Jamie Oliver and wife Jools recently welcomed baby No. 5.

The 41-year-old British celebrity chef announced in an Instagram post that he and Jools are proud parents to a newborn son.

"It's a baby boy! Everyone in the Oliver family is very surprised and beyond happy," he wrote. "He arrived safely, mum/@joolsoliver was really really amazing, unbelievably composed."

Oliver and Jools, who married in 2000, are already parents to 14-year-old Poppy, 13-year-old Daisy, 7-year-old Petal and 5-year-old Buddy. Poppy and Daisy joined their parents in the delivery room for their sibling's birth.

"My two eldest girls got to come in at the very end as the baby was born which was very emotional," Oliver said. "Love to all you mums out there how amazing you are it blows my mind ... p.s. no baby names yet."

Jools revealed in her own post that Poppy and Daisy cut the umbilical cord. Many were shocked by the couple's decision to include their children, but Jacque Gerrard, the Royal College of Midwives director in England, told the Guardian it is increasingly normal.

"Birth is a family event, and it affects everyone," he said. "With the right support and preparation, why shouldn't they be involved?"

Oliver is known for such shows as The Naked Chef, Jamie at Home and Jamie Oliver's Food Revolution. He has also appeared on Iron Chef America and Oprah's Big Give.
