They were horrific on the Hills, I was prepared to full on hate them on CBB, but they've turned it around for me.
I was firmly in Team LC when it came to the Hills (then Kristin, then Steph Pratt (Spencers older, ex-drug addict, but amazing sister)) but to be fair, once people stopped trying to meddle in their relationship, they seemed semi-normal. If someone did meddle in their relationship though, they got nasty!
