Yep, we couldn't quite believe it either...
Revealing he has never dabbled in a bit of DIY bronzing, Mark has admitted it took him four weeks on Strictly before he eventually gave in.
Speaking at the Bootea Shake launch, Essex boy Mark made the shocking revelation and claimed he only recently had his first ever fake tan.
He told Reveal: "I can categorically say that three weeks ago... I lost my spray tan virginity.
"I've never had a fake tan in my life. I've always been called perma-tan Mark anyway, so I've never had one and thought I'd stick [to not having one].
"But, when I started Strictly I said no to having a spray tan and the producers were like you're going to look so pale compared to everyone else. Steve, Jake they all had them, but I didn't. Then it got to the fourth week and I watched the show... I was really white."
Finally giving in, Mark decided to tan up and do Essex proud. But, he insisted it won't be a regular occurrence.
"I wouldn't have them everyday, though," he said. "Just for Strictly!!"
But, fake tan isn't the only thing Mark has taken a liking to lately...
Getting right into the Strictly spirit, the ex-TOWIE star confessed he has a new found love for sequins.
Mark added: "It's really weird when I started on the show, I went for my first fitting and they gave me Latin trousers and a sparkly top and I was like 'Woah! Take all that off and dress me how I am.'
"But now… I can't have a top without sparkles on. Week 2 I had to wear just a normal jumper and I was like, but it isn't sparkly… stick some sparkles on it!"
Dancing up a storm with his professional partner Karen Haeur, Mark has gone from strength to strength on Strictly lately. Despite finding himself in the bottom two quite early on in the show, the 27-year-old has bounced back and recently Mark has even found himself sitting in the leaderboard's top three.
But, does he think he has what it takes to take home Strictly's Mirrorball Trophy?
Insisting he hasn't let himself think that far ahead, Mark said: "I'm not even thinking about winning. I've won getting to this point.
"If I was to go now – obviously I don't want to – but if I did, I'm more than happy with my experience."
