Looks like the couple have continued with their theme...
But it looks like the couple might have finally revealed his moniker – and it’s as unusual as you might expect.
Mum-of-five Jools dropped a major hint when she posted an image on Instagram on Monday night featuring the words: ‘Dream Big River’
She then added a rocket emoji and a blue heart, appearing to confirm that the little one is called River Rocket.
Fans of the family seem to approve of the name, with lots of sweet comments appearing on Jools’ photo.
‘Lovely name and wonderful choice of announcement,’ one follower wrote, whilst another added: ‘Oh I LOVE his name! Welcome to the world River!’
Meanwhile one Instagram user joked: ‘And here I thought his name would be Steve’ LOLs.
Yep, the Olivers are certainly known for sticking to a theme when it comes to naming their children.
Chef Jamie, 41, and wife of 16 years Jools have always gone with nature-inspired monikers for their kids Poppy, 14, Daisy, 13, Petal, 7, and Buddy, 5.
At the time of the new arrival’s birth both Jamie and Jools, 41, said that they didn’t yet have a name for the tot but Jamie had previously hinted in an interview in July that they’d continue with the natural theme.
‘I think you can guarantee something floral or from the natural world,’ he told OK! magazine last month. ‘We might go with seasons this time – it’s going to be a little bit hippy, whatever happens.
‘I’ll pretend to have a say in the name, but I really have no say.’
Since his entrance into the world the little lad has popped up in some adorable Instagram pictures posted by his mum and dad Jamie even briefly took over Jools’ account to share a beautiful shot of mama and baby snoozing together.
‘bless them both sleeping and exhausted together I can’t tell you what a wicked mum this chick is,’ a proud Jamie wrote.
Awww – welcome to the world River!
