Katharine McPhee plays a pregnant Zeta Alpha Zeta. Rumer Wilis (Demi and Bruce's and Ashton's kid) plays a ZAZ who's back problem has healed but can't let go of her very visible back brace. Kiely Williams from Cheetah Girls and 3LW plays an (ugh...
) "Phi Mu" (Phi Iota Mu). The "Phi (Iota) Mus" are trying to kick ZAZ out of their house because their chapter is having major issues (recruitment and otherwise and they are social misfits). So you know these "Phi (Iota) Mus" aren't going to "represent" very well.
