Lisa Vanderpump’s staff will be returning for another round of mayhem with a fourth season of “Vanderpump Rules,” as Bravo has renewed the “Real Housewives of Beverly Hills” offshoot, Variety has learned exclusively.

Sources tell Variety that the series has been in production throughout the summer.

“Vanderpump Rules,” which follows the personal and professional lives of restaurateur Vanderpump’s staff at her chic L.A. restaurant SUR, has been among Bravo’s higher-rated and most consistent performers since it bowed in 2013. It typically draws between 1.5 million and 2 million viewers, with more than two-thirds of its audience falling in the key 18-49 demo.

From its debut in January 2013 to its third season that wrapped up this March, “Vanderpump Rules” has remained a success for the cabler through its three-season run with episode orders increasing season-to-season. The freshman round capped off at 10 episodes with the most recent tallying up to 21, including special reunion episodes, which have followed the finales each season.

The series hails from Bravo Media and Evolution Media, the production company behind Bravo’s “Real Housewives of Orange County” and “Real Housewives of Beverly Hills,” the latter of which launched the “Vanderpump Rules” spinoff. Vanderpump and Ken Todd serve as exec producers, along with Evolution’s Douglas Ross, Alex Baskin, Gregory B. Stewart and Bill Langworthy.
