Rob Estes to Exit 90210

West Beverly High will soon need a new principal.

90210 cast member Rob Estes, who plays the high school principal and Wilson family patriarch Harry, is leaving the show. "This is my final season on 90210 and I wish the show, cast and crew nothing but the best. I am looking forward to spending time with my kids and exploring other opportunities," Estes said in a statement.

Estes — who previously starred on the original Melrose Place — plays the father of main characters Annie Wilson (Shenae Grimes) and Dixon Wilson (Tristan Wilds). A show rep says Harry's departure will be explained.

"This is Rob's last season on 90210," the rep said. "He's a talented actor and we couldn't have asked for a better Harry Wilson. But if fans tune in, they'll understand why Rob's character is leaving."

News of Estes' exit follows Jennie Garth's announcement that she is "not really doing [90210] anymore," as she told Access Hollywood. Garth, the only series regular on both 90210 and its predecessor, Beverly Hills, 90210, told the site she's busy writing a children's book and developing a film with her husband, Twilight actor Peter Facinelli.
