Season 1 of The Real Housewives of Beverly Hills Even Has Lisa Rinna Saying "OMG"

Lisa Rinna joined the cast of The Real Housewives of Beverly Hills in Season 5, but that doesn't mean she doesn't have anything to say about the previous adventures of the 90210 squad. 

The RHOBH actress recently took to Twitter to express her feelings about the very first season of the series — and what she heard made even her jaw drop. "Talk about shady AF that first season of RHOBH OMG," Lisa tweeted.

But all in all, Lisa seems to be a fan of that inaugural season of RHOBH. We mean, who isn't? "Season 1 of RHOBH IS GOLD," Lisa tweeted.

Considering the fact that Season 1 of RHOBH included such iconic moments as the "Dinner Party from Hell," Kyle Richards and Camille Grammer's showdown in New York City, and Kyle and Kim Richards' limo fight, we'd definitely have to agree with that statement.
