43. Jacqueline Laurita (Real Housewives of New Jersey)
Has Jacqueline always been this volatile, or are we just noticing now? This year, Jacqueline appeared genuinely nasty in a way she never has before, repeatedly dragging up old drama with Melissa for no understandable reason. And even if Jax is truly just hurt by Teresa's indifference, her unstable, and at times frightening, behavior made us question whether she's gone too far to stick around.
