Alex admitted to Charles in an episode of Life On Marbs that she had been unfaithful, saying she slept with co-star Jeff Graham and also cheated with another mystery boy.
The boy in question was soon revealed to be TOWIE hunk Dan.
Now speaking to Reveal, Dan tells us: "I watched the episode. Someone rang me and said my name was brought up quite a few times, so I put it on.
"It's just one of those things," he continues. "We were all out there filming, we had a few drinks, things happened. I didn't know she had a boyfriend at the time, but, it's happened now, there's not much I can do about it."
Dan, who has spent most of the summer promoting his latest business venture, SwegBoard, says he hasn't been in contact with Alex since. He tells us: "Not at all, I haven't seen her at all."
Meanwhile, Alex told us this week about her fling with Dan: "Dan was chatting me up. We kissed at the club and one thing led to another really. He's a really nice, lovely boy, and very charming. He's obviously very handsome – which is where it went wrong.
"My biggest regret is jumping back into a relationship and hurting him [Charles], because I probably could have avoided that if I thought about how I actually felt."
