Tori Spelling may not be reprising Donna Martin on 90210.

But Jennie Garth and Shannen Doherty, as Kelly Taylor and Brenda Walsh, respectively, are officially back in the zip code that made them famous. You can even see them in action, briefly, in a new 90210 promo.

WHO ARE YOU MORE EXCITED TO SEE ON 90210, BRENDA OR KELLY?
