Naomi: I just didn't think it would be Jen who would break my heart.

Jen [to Naomi]: I think part of me is still jealous of you. You have so many people who just love you.

Jen: I don't steal things, I earn them.

Silver: I'm so not getting involved in this. Good luck and don't get arrested.

Naomi [about Ivy]: I said some hippie freaks were selling their crap; she probably wanted to go be with her people.

Ivy [to Diego]: Come to think of it maybe I will work with that sellout. At least she sees some sort of future with me.

Ivy [to Diego]: You know you sure have a lot of opinions about how I should live my life for somebody who is just a friend.

Adrianna [to Vanessa]: I'd rather have a job kissing Kim Kardashian's ass than ever work with you again.

Vanessa [to Liam]: Last time I checked movie stars don't do manual labor.
