Her name is Ivy, she's played by Gillian Zinser and the actress describes the West Beverly student as "atypical" in the interview below.

Ivy is a tomboy that joins the surf team and initially clashes with Liam. But these two will soon develop a rapport with one another, creating yet another obstacle for a reconciliation between Liam and Naomi.
