That night, the gang assembles for ShePratt's sequintastic birthday celebration. Brody and Sleazy T jokingly carry in Frankie as ShePratt's gift. And Holly's even there! With any luck, she will dance like nobody's watching. Someone's gotta pick up the slack now that ShePratt is court mandated to drink soft drinks. Kristin wastes no time in plopping down on Brody's lap, prompting Frankie to ask what their current status is re: Friends with Benefits. Brody says it depends on how many drinks they have. Kristin puts on a fake(?) drunkface and screams, "Bottom's up!" She laughs and tells BS to make sure she and Kristin go home together at the end of the night.

Just then, McThirdWheel comes in with her friend Allie Lutz. Apparently this Lutz character is one of Kristin's arch nemeses, or so her blurting out, "Shut the fuck up!" would suggest. While Brody tells Frankie to pipe down from desperately calling over McBuzzKill, Kristin talks trash about Lutz, proclaiming her "the dumbest girl on the planet." I'm up in the air as to whether she's dumb, but homegirl does not know the first thing about aesthetics. We're talkin' bleached-to-death blonde hair and brown, thick lip liner over frosted mauve lipstick. Ugh.

McBadLiar shuffles into the middle of the crowd and pretends she didn't realize Brody would be at the party. After they clack over the other side of the banquette, Audrina asks for the back-story on ol' Lip Liner Lutz. Brody says there was some sort of misunderstanding after someone stole a ring of her at one of his parties, so she broke into his house, woke him up, and demanded he give her ring back. Audrina wonders how she knows McMySpace.

Kristin interrupts to tell Brody that McStormCloud is giving him the evil eye. He acts all above it, calling her out for showing up where she wasn't invited (by him at least -- since he's the only person in this group) and not causing an overdramatic scene. Give it time, B... Kristin calls LiLi Lutz a "psycho bitch." At which point we pan across the banquette, and it becomes obvious that the gruesome twosome are, like, two feet away and can hear everything. LiLi Lutz claims she's here "supporting a friend." Kristin tells her to bugger off, explaining that she hates LiLi Lutz because of Brody and the break-in incident. LiLi Lutz claims her innocence, but Kristin's all, "I was in the bed, sweetheart." Ha! As the scene gets more heated, others begin to wonder who this trashbag L.A. Face is with McChooseYourFriendsWisely. They agree that she must not be a very classy broad if she hangs out with the likes of LiLi Lutz.
