Lady Gaga is famously a huge Bravo fan and even put the Real Housewives of Beverly Hills in her music video for "G.U.Y." Lady Gaga has also written on her social media accounts about watching Lisa Vanderpump's Bravo spin-off Vanderpump Rules.

After Richards' incredible experience with the "Bad Romance" singer, the reality TV star had to go back to Beverly Hills. "Such a fun weekend in Las Vegas with @MauricioUmansky at @CaesarsPalace," she wrote. No word if this vacation was filmed for Real Housewives of Beverly Hills, which is expected to come back to Bravo this fall.
