We reported earlier this month that Shannen Doherty was in talks to reprise her role as Brenda Walsh on “90210″ – well, now it’s official. Shannen Doherty has signed on to join the Beverly Hills, 90210 cast as a grown-up version of her character, Brenda Walsh.

Here’s hoping Shannen Doherty keeps the on-set catfighting to a minimum – after all, Jennie Garth will be reprising her role as Kelly Taylor on the revamped “90210.”

So, what happened to Brenda Walsh since she left West Beverly High School? Shannen Doherty will play Brenda Walsh – now a famous theater director who returns to her high school to stage a musical.

Will you tune in for the new “90210″ when it premieres September 2?
