Widely known as the cheeky chap from Blue Peter, 31-year-old Matt grew up on a sheep farm in County Durham and was a British gymnast as a child.
It was only when he was performing in a college production of Grease - "just to do some back flips and somersaults" - that a teacher took him aside and suggested he turn his attention to drama.
Soon after graduating from drama school in Edinburgh he found himself presenting Blue Peter alongside Katy Hill, Konnie Huq and Simon Thomas. He spent seven and a half years on the show, leaving in 2006.
"When I left Blue Peter I wanted to go off into the production side but I've never had the chance because I've been so busy," he laughs.
First came commentary for the BBC Gymnastics show, then he presented Crufts, followed by Animal Rescue Live and Countryfile Summer Diaries.
He admits he owes his career progression to the long running children's show.
"It's a shock to the system when you finish Blue Peter you're like 'wow that was incredible' because it was a constant ride. Really it's only now I start to remember the things I did because at the time I didn't have time to register a lot because it is so fast paced and there's so much going on," he says.
"Now it's funny to sit back and watch the programmes and it's like I'm having an outer body experience. I sit there watching the telly thinking 'is that me doing that?' It's really bizarre, I can't quite explain it."
Given his farming roots, it should come as no surprise that Matt is joining John Craven and Julia Bradley for the new series of Countryfile, which is moving to a prime time Sunday evening slot.
Matt can't wait to get started.
"Here I am doing Countryfile and it's incredible, because it's the adult version of Blue Peter. To still be passionate about the countryside having grown up in it, it's just wonderful to be able to go and broadcast about it and to have that connection, I must say it's my dream job."
He's genuinely excited about the new role and the chance to show himself off as a true country boy.
"When I moved down to London for Blue Peter I couldn't wait to get out. I moved to Chiswick first and then I moved out to Buckinghamshire and then when I got married, we moved further out into the countryside.
"I am one of those people who needs trees around. You don't really think about it growing up, and it's funny because I've just been writing an article about how much I took for granted my surroundings as a little boy. When you move away you suddenly realise how much it means to you and how important it is to have that feeling of space and natural stuff around you. I do feel that even if I don't end up back in Durham I'll certainly be out in the sticks somewhere."
Countryfile, which has been running since 1988, attempts to dispel the perceived 'us and them' attitude between rural folk and city dwellers.
"I just want people to feel a connection and go out to the countryside and not necessarily feel daunted by what it is. It's an incredible place which we can go out and enjoy," Matt says.
"It seems a bit funny because a huge amount of Britain is countryside and within it are these little towns, and people don't realise how accessible the countryside is. Britain is an agricultural place, we create our own food, and I think especially now there's a real push towards rural recreation - just getting out and enjoying the countryside."
While he's doing his best to change attitudes, you can expect to see another familiar face helping out every now and then. Matt's hoping to bring his dog Meg, who regularly featured on Blue Peter, out of her TV retirement for the series.
He's busy off-screen too. Matt and his wife Nicola already have a two-year-old son and are expecting another baby in August.
"I couldn't do Blue Peter now with a family, I'd just never see them," he says.
"I must say at the moment things are going great and I can't complain."
