Jackie Taylor has a lot of explaining to do.

The last time this character was seen in Beverly Hills, she was drunk, dating a man half her age and essentially throwing daughter Silver out of the house.

Fortunately, Entertainment Weekly reports that Ann Gillespie has signed on to reprise her role on 90210 as Kelly and Silver’s train wreck of a mother.

Michael Ausiello writes that the actress will return for multiple episodes, the first of which takes place in October. An insider told the TV columnist that the character comes back “to mend the broken relationships with her daughters, with several shocking surprises.”
