*TV Guide is reporting that Megalyn Echikunwoke has joined the cast of the CW’s “90210”as a new nemesis for Naomi, played by AnnaLynne McCord.

The actress will play Holly, a character described by TV Guide as “the mean-girl president of the most prestigious sorority at CU.

“When Holly can’t control Naomi’s characteristic acquisitiveness, she seeks revenge for one particular purchase by hazing the holy heck out of everyone’s favorite pregnant frenemy.”

Echikunwoke’s previous credits include “CSI: Miami,” “The 4400” and “24.”
