A “Bel-Air” spinoff is in the works at Peacock.

“Hilary,” an offshoot of the Will Smith-inspired drama series starring Coco Jones, is in development at the streamer. The project hails from writer-producer Tracy Oliver, co-writer of “Girls Trip” and “Little.”

If the series moves forward, “Bel-Air” will become Peacock’s first scripted original series to get a spinoff.

Jones played Will Smith’s (Jabari Banks) cousin Hilary Banks across all four seasons of “Bel-Air,” a dramatic reimagining of “The Fresh Prince of Bel-Air” that became a breakout hit for Peacock. The show followed Will Smith’s journey from the streets of West Philadelphia to the luxurious gated mansions of Bel-Air. (We all know the song…)

The logline of “Hilary” reads, “After accepting an unexpected job offer from celebrity chef Yvonne Durand, Hilary Banks impulsively moves to New York determined to prove herself beyond her Bel-Air connections — only to find that success, friendship and love in the city come with a cost she never anticipated.”

Jones and Oliver executive produce “Hilary” alongside Will Smith, Terence Carter, David Boorstein and Miguel Melendez of Westbrook Studios; Benny Medina, Andy Borowitz, Susan Borowitz, Morgan Cooper, the Jeff Pollack trust and the Quincy Jones estate.

In addition to work on “Bel-Air,” Jones got her start as a child actor on Disney’s “So Random” and “Let It Shine.” Her credits also include “Vampires vs. the Bronx” and “Strung,” and she is the Grammy-winning singer behind the hit R&B song “ICU.”

With “Girls Trip,” Oliver became the first Black woman to write a film that grossed more than $100 million at the global box office. Her credits also include “The Sun Is Also a Star” and “The Blackening.”
