There is a chance that Mary-Louise Parker will not return for a seventh season of "Weeds". NY Post is reporting that the lead actress of the Showtime series is looking forward to quit the show once the sixth season ends.

The show is currently in hiatus to welcome the fifth season in June. Showtime has ordered both fifth and sixth season for 13 episodes each. However, it could as well end in the sixth as an insider was quoted as saying that there would be no point in continuing without Parker. "We'd have to see if it made sense to continue, but we can't envision the show without her," said the insider.

Parker is under contract until sixth season but plans to exit after fulfilling the obligation. No reason or comment from the actress or rep have been put out for this and also, the insider added that there is no talk taking place between Showtime and Parker.

While the show may lose one of its members in the future, the fifth season swells with the addition of Jennifer Jason Leigh as Nancy's estranged older sister. Leigh will be in at least two episodes, playing Jill who is confided by Nancy to take care of her son Shane.
