This week on the Real Housewives of Orange County: Gina invites the women over for her housewarming. Tamra gives an update on Teddi. Jenn is irate about the "fatty photo" and takes it out on Heather. Tamra and Gretchen get into it. Gina plans a New Orleans trip for the ladies. They all have a fun time on the first night of the trip...before things go horribly left.
