Congratulations are in order for Gillian Zinser. The actress has been promoted to series regular on 90210.

Zinser debuted on the show toward the end of 2009. We thought her character's introduction and subsequent love/hate relationship with Liam felt forced, but Ivy eventually settled into her role on the series.

She now makes for the ideal foil for Naomi, as a promo for the second half of the season makes it look like as though these two aren't done fighting over Liam. Not one bit.

Are you happy Zinser is now a regular part of the 90210 cast? Do you wanna see Ivy or Naomi end up with Liam? Sound off now!
