"90210" veteran Jennie Garth tells Ryan Seacrest on his radio show that the new version of the series will not disappoint the show's biggest fans, with shocking story lines to define the series for the new millennium.

Garth said during the interview on KIIS-FM that while in the beginning she "wasn't too big on the idea" of coming back for the new '90210,' she realized that so many fans grew up with the show and are so devoted to it that she became excited to be a part of it.

Garth and Shannen Doherty are the only returning cast members from the original series, and Garth played down any tensions that occurred in the past between the two stars.

"It was pretty silly, if you step back and look at it. That was so long ago, and things that were said -- I can't even remember feeling that way, or why it all happened," Garth said. She said the two went into the new working relationship "with a positive, fresh perspective."

Garth also said she would be thrilled if additional original cast members joined the new cast, but said that as far as she knows, only Tori Spelling is actively in talks to come back. "90210" premieres tonight at 8 p.m. on the CW.
