It's Christmas on The Real Housewives of Orange County!

Tamra and Heather, along with their husbands, attend an Ugly Sweater party and Tamra whines the whole time about how unfortunate it is that she had to--gasp!--attend a themed party.

(Hey, Tamra, remember that 80s party you threw? No?)

Elsewhere on The Real Housewives of Orange County Season 9 Episode 4, Vicki and Brooks go to dinner to discuss her most recent chat with Briana. Red flags about Brooks continue to go up for everyone except Vicki when he says he isn't interested in spending time with her friends or family.

And then there's that new housewife on the block! Watch The Real Housewives of Orange County online now to meet Lizzie Rovsek!
