Kelly Taylor and Brenda Walsh really are returning to 90210.

We reported this awhile ago, of course, but anyone having doubts about the exciting news simply has to watch the video below. It's the show's first promo to feature shots of the characters.

Near the end, Kelly tells new principal Harry Mills (Rob Estes): "You know how kids in Beverly Hills are."

We know how at least two of them are, Kel. And we can't wait to watch them in action again!

As a brief 90210 spoiler:

Kelly and Brenda are rumored to be fighting over a guy not named Dylan McKay on the series. Reports have said these two will both vie for the attention of teacher Ryan Matthews (Ryan Eggold).
