MUMBAI: Pop star Britney Spears will guest star on US broadcaster NBC's sitcom Will And Grace.

She guest-stars as a Christian conservative sidekick to Jack played by Sean Hayes. In the episode, when "Out TV" is bought by a Christian Television Network, Spears is brought on to be Jack's new religious co-host, until Will played by Eric McCormack and Jack loosen her up. Spears brings her own additions to the talk show when she decides to do a cooking segment called "Cruci-fixin's."

Dubbed by MTV as "one of the last teenage pop superstars of the 20th century," Spears enjoyed her breakthrough success at the end of 1998. She appeared in local dance revues and church choirs as a young girl, and at the age of eight, auditioned for "The Mickey Mouse Club." Although she was too young to join the series, a producer on the show gave her an introduction to a New York agent. She subsequently spent three summers at the Professional Performing Arts School Center.
