Gabby Deveaux is first introduced as the on again off again love interest of Alice during season 1. It is clear that Gabby is manipulative and untrustworthy, but Alice keeps coming back despite her friends' warnings that she is no good. After a nasty breakup, the two become increasingly hostile towards one another. Throughout the earlier seasons, Gabby makes several appearances, often as Alice's adversary.
In the first episode of season 6, Alice follows Tasha to Papi's house where she finds Gabby hooking up with Papi. Gabby and Alice exchange some harsh remarks, including Gabby calling Alice the 'crasher' (because she used to show up at parties she wasn't invited to).
