Pardon us if we don't see the resemblance: "Beverly Hills 90210" alum Jennie Garth has signed on to star in "Nancy Grace's Eleventh Victim," an adaptation of Grace's semi-autobiographical debut novel.

Garth will play Atlanta assistant district attorney Hailey Dean, whose fiancé is murdered. Then she wins the conviction of a serial killer (Clint Burrell Cruise, in the tradition of serial killers with three names) and moves to New York City to begin a new career as a therapist.

In Grace's novel, "The Eleventh Victim," Dean's therapy patients become victims of a murderer who operates much like Cruise did. Dean, somehow unaware that Cruise had been freed from prison after an appeal, becomes the suspect in the murders.

Grace, whose fiancé was murdered when she was 19 and who worked in the Atlanta district attorney's office as a prosecutor who specialized in serial killer cases, will act as an executive producer on the movie with Ted Bauman and Josh Sabarra.

Garth, who, like Grace, is a "Dancing With the Stars" alum, is also currently starring in a new CMT reality series - "Jennie Garth: A Little Bit Country" - which follows her family's move from Los Angeles to a working farm.
