Tv bosses behind How I Met Your Mother are planning a spin-off, according to U.S. reports.

The hit sitcom, which stars Neil Patrick Harris, Jason Segel and Alyson Hannigan, is in the midst of its ninth and final season, but creators Carter Bays and Craig Thomas may continue their reign on television with a new show.

Bays and Thomas, along with former Saturday Night Live writer Emily Spivey, have pitched an all-female comedy called How I Met Your Father, according to Entertainment Weekly.

Like its predecessor, the spin-off would tell the tale of a group of friends living in New York and follow the main character's journey to meeting her future husband. If the project is greenlighted, the new cast of characters would likely be introduced in the series finale next spring (14).

How I Met Your Mother has been one of America's top-rated shows for the past eight years.
