A sign posted on the outside window of The Cairn Coffee House Tuesday warned visitors that by entering the building they may end up on a television program.

Taryn Benesta, a producer with Evolution Film and Tape, said the crews were filming a show for the Bravo Network. The show does not yet have a title, she said.

Benesta said crews will be in town until Oct. 28.

The crew included at least two camera operators, production assistants, producers and support staff with various pieces of film and sound equipment.

While Benesta said she could not confirm what show was being recorded, some celebrity gossip websites including radaronline.com have reported reality TV stars Jax Taylor and Brittany Cartwright, a 2007 graduated of George Rogers Clark High School and Winchester native, have begun filming a spinoff to the show Vanderpump Rules in Cartwright’s hometown.

Benesta said the show being filmed will feature 30-minute episodes, and more information may be available in the future as filming continues in Winchester.
