Dimitri Portwood Kutcher might be the coolest kid on Earth - not just for his name - but because of his vintage That '70s Show t-shirt emblazoned with the faces of his mum and dad, Ashton and Mila Kunis.

The adorable Hollywood couple rarely share photos of their children on social media, but obviously agreed to make an exception after dressing their son in a classic Jackie and Kelso tee with the tagline 'Hello Wisconsin'.

'Yes,this is my son's outfit today.#that70sshow #kelsoandjackieforever,' the No Strings Attached star captioned the pic.

But where can we get our hands on the tee in adult size?

He and Kunis - who first met on the US comedy show in 1998 - welcomed Dimitri in November last year, the couple's second child following the arrival of their daughter Wyatt in October 2014.

Kutcher - who initially wanted to call his son Hawkeye - recently explained it was Kunis who came up with the less unusual suggestion of Dimitri.

Speaking on The Ellen Degeneres Show, he revealed it all began with the Black Swan star's prediction Donald Trump was going to become president.

'We're on our way to date night, and Mila turns to me and she goes, 'So, I think Donald Trump is going to become the President, and I think our baby's name is Dimitri,' he recounted.

'I was like, 'Donald Trump's not going to win the.... And then I forgot about the name thing because I was like, 'Why do you think Donald Trump is going to win?' I'm telling you, she called it! It's not even a joke."

The Ranch actor continued: 'Two weeks later, I got home from work, and for some reason the name just stuck in my head.

'I was like, 'I think Dimitri is the name of the baby.' And she was like, 'I know, right?' 'Yeah, that's it!' So, that's it. And then Trump became President. Everything Mila says is right! She's my wife, so that's just what it is.

'Everything she says is right.'

We don't doubt it...
