The name River is particularly dear to the cooking legend, who made his big splash while working as a sous chef in the acclaimed River Café in Fulham back in 1997.
The BBC took notice of the talented young chef and gave him a role in one of their documentaries. Two years later, he was the star of him show The Naked Chef... and the rest is history!
Jools previously told Gurgle that she loves having fun with naming her kids.
"They all have more than one name because I couldn't decide. I'm not sure where Petal Rainbow came from – apparently it's a My Little Pony! I wanted to call her Rainbow but Jamie told me to calm down."
"With Buddy it was quite fun choosing a boy's name, as I hadn't done it before. And I hate people's opinions on names. Whatever you call your baby is your decision."
