Well, we here have all known he fancies Alfie and has for a long time.Mark just did a Q&A on his stories and someone asked ;if Zoe and Alfie split up would you get with Zoe?' and Mark replied 'your barking up the wrong tree there'.
Just because I think it would be the most interesting thing to happen to the three of them in so long, I would love to see Zoe and Alfie break up, and Alfie get with Mark instead of a generic Insta model. At least Alfie and Mark have chemistry.
