Thesp Diane Farr (“The Job”) has joined the cast of the upcoming WB sitcom “Like Family,” starring opposite Holly Robinson Peete.

Farr will play Maddie, a newly single, down-on-her-luck mother who winds up taking her 16-year-old son and moving in with the family of her best friend (Robinson Peete). Farr replaces Amy Yasbeck, who played the character in the show’s pilot.

Farr is coming off a busy pilot season, having booked two projects and developed a third. The actress starred in NBC pilot “The Ripples,” in which she and Adam Arkin played a couple that have been married for 4,000 years.

She also appeared in the CBS pilot “Harry’s Girl,” playing the best friend of Christine Taylor’s character. She also developed a project for ABC, through Warner Bros. TV, based on her experiences growing up with a multi-ethnic crew in Brooklyn.

Beyond acting, Farr is also working on her second book. Farr previously authored “The Girl Code: The Secret Language of Single Women on Dating, Sex, Shopping And…”

Farr’s varied resume includes her two seasons on “The Job” alongside Denis Leary; recurring roles on “Roswell” and “The Drew Carey Show”; and a two-year sidekick gig on MTV’s “Loveline.”

Farr, who’s repped by WMA, Steven Fenton and Todd Rubenstein, has also served as a columnist for magazines including Cosmopolitan.

Beyond Robinson Peete and Farr, “Like Family” also stars Kevin Michael Richardson, J. Mack Slaughter, J. Anthony Brown, Megalyn Echikunwoke and B.J. Mitchell. Laffer comes from Warner Bros. TV.
