The 35-year-old presented in the interactive “Hub” on This Morning, before making the move to Channel 5 to co-host OK! TV.
But, the TV star opened up about his time on the ITV show to Express.co.uk recently, where he spilled all about why he once stripped off for a live broadcast.
Explaining how the incident arose, Matt revealed that he and This Morning chef Gino D'Acampo had placed a bet with each other after the daytime TV programme was nominated for its first National Television Award back in 2011.
Recalling the moment, he said: “I didn’t have a clue what the bet really was.
“Gino and I placed a bet so that if we won, we’d host the show nude.Related articles
It was one of the worst moments of my life and one of the best as well.
“We ended up winning, and we ended up doing it nude,” he continued.
Staying true to his pledge, Matt flashed the flesh during an episode of the show, which saw him cover his modesty with a well-placed laptop on a cushion.
Speaking to hosts Ruth Langsford and Eamonn Holmes at the time, he said: “A promise is a promise.”
Reminiscing about the moment, the Welsh presenter went on: “It was one of the worst moments of my life and one of the best as well. It’s a funny thing to look back on.
Laughing about being naked during a segment of the show, he added: “What an idiot. I wouldn’t recommend it to anyone.”
