Sunday was a very good night for The Real Housewives Of Atlanta and Shahs Of Sunset. Bravo had its best primetime ever last night and strongest Sunday ever among adults 18-49. That was in great part to its 8 PM and 9 PM offerings: The Southern-based Housewives had its highest-rated episode of the season with 3.7 million viewers. That eclipsed the record 3.2 million that watched the show’s Season 5 premiere on November 4. Also on Sunday, Shahs Of Sunset drew a series high for the LA-based show. The Ryan Seacrest-produced reality series pulled in 2.5 million viewers and was up 62% in the 18-49 demo compared to Season 1’s sixth episode.

Meanwhile, the premiere of the Andy Cohen-hosted Watch What Happens Live drew 1.7 million viewers, 1 million in the 18-49 demo, while the 10 PM premiere of Vanderpump Rules delivered 1.9 million overall viewers, more than 1 million in the 18-49 and 1.2 million among adults 25-54. Those numbers made Vanderpump Rules Bravo’s highest-rated series launch since the May 10, 2010 debut of Bethenny Getting Married?
