I am only on Season 2 as well. I just watch it open-mouthed really. All of the women seem to be extraordinarily bitchy, particularly Chloe's and Paige's mum. And their jealousy of Maddy. My goodness. Talk about over-invested in your kids.
They do meet and greets sometimes. Kelly and Christi (plus Chloe, Paige and Brooke) do lots together and they are really nice in real life. Very friendly, get on well and it's very revealing what they have said about the show and which parts are totally real and which are helped along by producers suggestions!!
Kelly also talked about the fact that they are not allowed to leave the studio as they are all locked in to contracts till season 6!
