Jennie Garth may be heading for the hills—the Beverly Hills.

Buzz is mounting that the erstwhile Kelly Taylor may be the first West Beverly High alum to return to the old ZIP code after Garth abruptly pulled out of a CBS comedy pilot that went into production this week.

Last month it was announced that the former Beverly Hills, 90210 fixture had joined the cast of My Best Friend's Girl as a woman who begins to date her ex-husband's best friend.

The gig didn't last long as, per the Hollywood Reporter, Garth and the producers mutually agreed to part ways shortly after completing Monday's table read. No official reason was given for the amicable split, but Garth has recently been dealing with the death of her father, who passed away after she had been cast in the project.

Canadian actress Kristin Booth has since replaced Garth, and with her schedule now free and clear, she is definitely available for the 90210 spinoff.

Last month it was announced that the CW was developing a contemporary spinoff of the seminal teen soap, with Veronica Mars creator Rob Thomas heading up the project.

Though Thomas has since put his contribution to the show on the back burner to work on two other series, he remains an executive producer on the pilot and has been attending casting sessions for the series as well as actively recruiting Garth to join the cast, as first reported by E! Online's TV blog.

No other series alums have yet been cast, though former Runaway thesp Dustin Milligan

was the first actor to sign on to the series last month, starring as Ethan, a popular star athlete.

According to the trade, should Garth reprise her Kelly Taylor persona for the pilot and beyond, the likeable character would likely return as a fashion design teacher at her old alma mater.
