Amalia Zinser

Amalia Zinser has been cast as Ivy, a surfer chick who will tempt 90210's guys, TVGuide.com has learned exclusively.

Tomboy Ivy is just one of West Bev's guys, and as such she'll flirt with both Dixon and Liam (which doesn't bode well for Silver and Naomi) at the beach. "She's the quintessential California girl — easy-going, athletic and full of fun," says a mole. Ivy's first appearance will be in October.

Though Zinser is a relative newcomer to Hollywood, you might recognize her from recent guest-starring gigs on Cold Case, Southland and Cupid.

The second season of 90210 begins on Tuesday, Sept. 8 at 8/7c on the CW.
