‘Two and a Half Men’ Co-Creator Lee Aronsohn Steps Down as Showrunner

Co-creator and co-showrunner of "Two and a Half Men" will likely stay on as an executive cosultant; Executive producers Don Reo and Jim Patterson are in talks to take his place

There's been another "Two and a Half Men" shakeup — but this one has nothing to do with volatile cast members.

Lee Aronsohn, who created the hit CBS series with Chuck Lorre, is stepping down as the series' showrunner, an individual with knowledge of the decision confirms to TheWrap.

Aronsohn, who has been with the series for nine years, is in final negotiations to remain on as an executive consultant for the show.

No reason was given for Aronsohn's decision.

Don Reo and Jim Patterson, who began serving as executive producers for the series in 2011, in time for Ashton Kutcher's replacement of series star Charlie Sheen, are in final talks to become co-show runners with Lorre. (Patterson has been involved with the series in a variety of capacities since 2005.)

"Two and a Half Men" executive producer Eddie Gorodetsky is expected to remain on the series, as well as to maintain his duties as consulting producer on Lorre's other hit series, "The Big Bang Theory." 

All of this is pending CBS' renewal of the series for a 10th season, which has not yet been formally announced.
