In an interview, former 'TOWIE' star Lauren had said that they enjoyed a "secret life".
"Until about two months ago, we were still speaking to each other quite a lot, but it got confusing because we weren't officially back together again, so we're going our separate ways now. It's for the best," she told New! magazine.
However, Mark paints a much different version of events...
The 'Take Me Out: The Gossip' host took to Twitter to fiercely deny Lauren's claims, branding them "bullsh*t", saying that she was using him to get press.
He tweeted: "What absolute made up bullshit by Lauren in today's New Mag, I'm so bored of it, get over it & Stop talking about me 2 get yourself press !!"
Lauren had also said that she and Mark were "friends" in the interview, but we're guessing that could have changed by now...
