"It is going to be great," she told Usmagazine.com Saturday at the Much Love Animal Rescue's "Bow Wow WOW!" event in L.A. "The fans have been wanting this for a long time."
Doherty will reprise her role as Brenda Walsh, who, after a successful theater career, has returned to West Beverly High as a guest director for the school’s musical production.
"She is a huge part [of the show]," Spelling said of Doherty. "Any original cast member is huge to the fans. She was there from the beginning. She was 90210. Shannen and Jason [Priestley] - they were the Walshes."
She also says her father, the late Aaron Spelling, would have approved of the spin-off.
"He would be really proud," she told Us. "He always intended to do a 90210 next generation. He would want his hands all over it."
