NBC‘s Parks & Recreation may have been renewed for 22 episodes, but two of its co-stars, Rob Lowe and Rashida Jones, are only staying for the first 13. Lowe and Jones are set to exit the off-beat comedy halfway through Parks & Recreation‘s upcoming sixth season. I hear NBC is looking to keep Lowe in the fold, finalizing a development deal with an actor for a potential new series. Meanwhile, Jones has been ramping up her producing career, setting her production company with Will McCormack at Warner Bros. TV and tapping Wonderland Sound and Vision’s Jeff Grosvenor to run it. Jones was the first actor to join Amy Poehler on Parks & Rec (then still perceived to be an Office spinoff). Lowe, who next stars in National Geographic’s Killing Kennedy, joined as a guest star at the end of Season 2. Their characters share a storyline on the show — they’re having a baby. The duo’s departure was first reported by Buzzfeed. Season 6 of Parks & Recreation launches on September 26 with the daunting task of its hour-long premiere facing the hour-long season opener of CBS’ The Big Bang Theory.
