A riot almost broke out when Donna Martin was barred from graduating from West Beverly.

We can only wonder what sort of reception this character will receive now that she's confirmed to return to the zip code that made her famous.

Indeed, multiple sources - from Us Weekly to TV Guide - have confirmed that Tori Spelling and The CW have reached an agreement for the actress to reprise her role from Beverly Hills, 90210.

Not much is known about Spelling's role on the show, though her rumored first episode wil be directed by Jason Priestley and will air on March 18. Earlier this season, Kelly and Brenda mentioned that Donna is a mother.

Is David Silver the father? How will this be used in Martin's return to 90210? We'll have to tune in and find out!
