It seems Jamie Oliver has finally revealed the name of his new baby son.

He and his wife Jools had been keeping fans guessing, but a post on Instagram suggests the two-week-old is called River Rocket.

He is the pair's fifth child.

They already have Poppy Honey Rosie, Daisy Boo Pamela, Petal Blossom Rainbow and Buddy Bear Maurice.

Jools and Jamie Oliver leave the Portland Hospital in central London with the newest addition to the Oliver family.
