All of the nastiness that used to be Brenda Walsh in the form of Shannen Doherty will be back!  The rumors are now confirmed and Shannen will appear on the new 90210 series. 

More pictures after the jump…

Shannen has agreed to be a part of the new series.  E! Online says she will be called back to her alma mater to direct a school musical, since she is a successful actress (her character anyway).
