Lisa Kudrow is not returning to Showtime for more “Web Therapy.”

Showtime boss David Nevins confirmed that the series will not be coming back for a fifth season, telling Variety and other reporters that the show is done, Tuesday at the cabler’s Television Critics Assn. presentation in Beverly Hills.

The comedy, based on the web series of the same name, starred Kudrow as Fiona Wallice, a therapist who has conceived of a new form of therapy, hence the titular “web therapy.” Kudrow created the series with her producing partners Dan Bucatinsky (“Scandal”) and Dan Roos.

Conan O’Brien, Billy Crystal, Jon Hamm, Gwyneth Paltrow, Molly Shannon, Steve Carell, Jane Lynch and Kudrow’s “Friends” alums Courteney Cox, Matthew Perry, David Schwimmer and Matt LeBlanc were among the series’ guest stars.

Premiering in July 2011, “Web Therapy” wrapped up its fourth season this January, though it did not rank among the top 125 shows of the night.
