Former Will & Grace co-stars Megan Mullally and Sean Hayes are set to star in a spin-off of the hit comedy. The pair will reprise their camp double-act in "Karen & Jack," which is currently in development at network NBC.

According to sources, Hayes was keen on a spin-off soon after "Will & Grace" ended in 2006 - but was put off by the failure of Matt LeBlanc's Friends follow-up Joey. Plans were then derailed when Mullally landed a talk show - but that flopped, throwing the pair back together again.

The insider tells the National Enquirer, "They feel there is still a lot of life left in their characters and a lot of comic possibilities."

If a pilot episode is successful, "Karen & Jack" could be on the air in the next autumn.
