Although 90210′s only been around for three seasons, they sure do clean house (seemingly) often. Check out which two 90210 series regulars will no longer be appearing alongside our 90210 gang.
Ryan Eggold (who plays teacher Ryan Matthews) and Lori Loughlin (Mama Debbie Wilson) will no longer be returning to our favorite zip code, 90210. These two will exit at the end of the season. The show’s rep said that 90210′s 4th season will be characterized by the 90210 gang transitioning into college so there’ll be little emphasis on teachers or parents.
With Jennie Garth’s and Rob Estes’s departures last season coupled with Eggold’s and Loughlin’s departures season will leave 90210 with no adults. Yikes! Get ready for some crazy parent-free 90210 college shenanigans!
