for the life of me, can somebody please explain...

i'm watching the reacting to the city with Whitney Port and her husband Tim for the life of me can somebody please explain to me why they are so overly nice to Olivia on these episodes. Olivia is such a bitch but they keep praising her. It's just weird after all she did to Whitney. I'm just confused by this? I don't care what anybody says. I don't like her. I'm sure there's a lot of Olivia supporters here but she was a straight up bitch to Whitney. F that🙄😏
