A former American Idol finalist will touch down in Beverly Hills next week.

On "Benefit of the Doubt," previewed HERE, Kellie Pickler guest stars as Sally, an acquaintance of Austin's who signs up for a fundraiser, but doesn't exactly make a great first impression on Naomi. Watch the two get introduced in this sneak peek:

Elsewhere on the episode, look for Liam to get offered a job; Annie to develop an unexpected crush; Raj to receive bad news; and Adrianna to confront Dixon over his growing drug problem.
