Sarah Hagan

Buffy the Vampire Slater‘s Sarah Hagan (she played Potential Slayer Amanda during the show’s final season) has booked a recurring role on 90210, sources confirm to TVLine exclusively.

Hagan will play Alana, one of Naomi’s new sorority sisters at California University. The character is described as a born leader who proudly flaunts her extensive vocabulary and book smarts.

The actress — fondly remembered by Freaks and Geeks fans as Linda Cardellini’s straight arrow BFF Millie — joins a 90210 guest cast that also includes Justin Deeley as a love interest for Naomi and CSI: Miami‘s Megalyn Echikunwoke as Naomi’s CU nemesis.

90210 kicks off its fourth season on Tuesday, Sept. 13.
