Shar Jackson is in the middle of another family drama, but this time it’s fictional. The mother of two of Kevin Federline’s four children will guest star on the CW’s Everybody Hates Chris, she tells PEOPLE exclusively.

“I am having a blast,” Jackson tells PEOPLE. “The cast is absolutely amazing.”

In the episode, Jackson’s character Alyson is a young mother whose teenage daughter uses Chris’s sister as a cover to sneak into an R-rated movie and visit a boy’s house. Chris’s mother Rochelle, played by Tichina Arnold, takes Alyson aside to confront her about being a better role model.

Choreographer Debbie Allen is directing the episode, which will air sometime after the third season’s Oct. 1 premiere.

Jackson, whose defining role was playing Brandy’s best friend Niecy Jackson on UPN’s Moesha, recently co-hosted the reality show The Ex-Wives Club with Marla Maples and Angie Everhart.
