This is effectively two punch drunk boxers beating themselves to death while the referee laments it all but won't call it off as the crowd bay for more. Chantelle and Alex are the boxers, the media is the referee and the people that indulge in this trash are the crowd. Or two rats fighting over a single morsel to feed themselves, with Dolly as that morsel. Take your pick.
Honestly, they both got famous for shagging people, one called Preston and the other called Jordan, so they could make money from the experience. They define the term fame whores literally.
