Beverly Hills, 90210 premiered in 1990 and nearly 30 years later, we'll get to see seven of the main cast members -- Jennie Garth, Gabrielle Carteris, Shannen Doherty, Brian Austin Green, Jason Priestley, Tori Spelling and Ian Ziering -- reunited once again for the meta reboot, BH90210. Before you grab your hairspray, get settled in at the Peach Pit and perfect your "Donna Martin graduates!" chant ahead of the Aug. 7 premiere, let's take a look back at what the actors looked like when we first met them and where they're at now.
