The countdown continues to the premiere of The CW's new "90210" spin-off with ETonline's Web exclusive of clips from the original "Beverly Hills, 90210."

Return to where it all began: Tonight's video flashback is really that. It is a scene from the pilot episode, "The Class of Beverly Hills." In it, the gang goes to a party and Kelly (Jennie Garth) explains to Brenda (Shannen Doherty) that she broke up with Steve (Ian Ziering), while Steve tells Dylan (Jason Priestly) that he dumped Kelly. Oh, yes. And Kelly shows off her new plastic surgery!

Before the launch of the new series, SOAPnet will celebrate the original Aaron Spelling show with a 24-hour marathon, starting at midnight on Monday, Sept. 1 -- with ETonline giving you a sneak peek of the episodes that will air!

Then, on Tuesday, Sept. 2 at 8 p.m., the all-new "90210," starring Rob Estes, Lori Loughlin, Shenae Grimes, Tristan Wilds and Jennie Garth will premiere with a special two-hour episode on The CW when the Wilson family moves to Beverly Hills.
