Two 90210 stars leaving the show

According to this article, Rob Estes and Jennie Garth are no longer steady cast members of the CW's 90210. Estes will leave as of the end of the season and, apparently, there will be an explanation that makes sense. As for Garth, in a recent interview she mentioned that she is not really doing the show anymore. And in other 90210 news, this article announces that Gilmore Girls alum Scott Patterson will appear as Liam's father for a multiple episode stint when the show returns this spring.
