Jamie Oliver and his wife Jools welcomed their fifth child recently, joining older siblings Poppy Honey Rosie, Daisy Boo Pamela, Petal Blossom Rainbow and Buddy Bear Maurice.
In true Oliver style, the doting parents have chosen an equally unique name for their youngest child: River Rocket.
Jools announced the news on Instagram this week, sharing a photo of wall art in the baby's nursery that read 'Dream Big River'.
