Rosie Huntington-Whiteley has confirmed that she has welcomed her first child with fiancé Jason Statham.

And, just as she did to announce the pregnancy in the first place (remember that beach snap?), she’s done so via her Instagram account.

Sharing a black-and-white photo of her little boy’s hand, Huntington-Whiteley wrote: “Our little man arrived!”

She went on to confirm her son’s incredibly traditional name, as well as his birthday, writing: “Jack Oscar Statham 8.8lbs on Saturday June 24^th.”

Of course, you may be wondering about the meaning behind that moniker.

Jack is a cheery-sounding name, and an increasingly popular choice among parents, which means that it never strays too far from the upper half of the top 100 baby name lists. Despite being a ‘nickname’ (it’s an alternative to John), it still feels old-fashioned – and is imbued with biblical meaning, too: “God is gracious”.

Oscar, on the other hand, is a far more unusual choice. Dubbed a “grandpa name” by many for a long time, it has been slowly creeping up the popularity stakes. However it hasn’t yet quite made it into the top 100 (it was named the 176th most popular baby name in 2016).

Even more interesting, though, is the meaning behind this Irish name: “champion” and “friend to deer”.

In Celtic legends and mythology, Oscar – son of Oisin and the fairy woman Niamh – was one of the mightiest warriors of his generation, and served as a fiann under his grandfather, the famous Fionn mac Cumhaill.

So, all in all, it’s a pretty powerful name choice from Huntington-Whiteley and Statham.

Huntington-Whiteley and Statham have been together since 2010, getting engaged in January last year – and the model has previously spoken of wanting to start a family with the Mad Max star.

Speaking to The EDIT in 2015, Rosie said: “Having a family is something I think about for sure, and whether I'd live here in America or in England. But it's not always as simple as that.

“I have no idea what will happen, but it'll be interesting to find out, right? And nothing will be perfect, I'm sure.”

Three years earlier, Huntington-Whiteley told Elle there would come a time in her career when motherhood would take priority over modelling.

“I always see myself working, but definitely being a mum will be a big part of me,” she said. “I think there is naturally a point where you think, ‘I don’t care about myself as number one any more.’

“’I want to care about other things.'”
