Season 7 of THE REAL HOUSEWIVES OF BEVERLY HILLS premieres tonight on Bravo, and Eileen Davidson (Ashley, Y&R) and Lisa Rinna (ex-Billie, DAYS) will, once again, be in the thick of things. “Here we go again,” Davidson tweeted. RHOBH co-star, Erika Girardi, who will appear on Y&R on December 15 as a birthday gift from Davidson, tells Digest, “I think it’ll be a great season! You’ll be entertained for sure. There’s a lot of travel, a lot of lifestyle, a lot of fun. There’s two new personalities in the show, so there’s some new drama happening, new dynamics, and I get a little bit more personal this year and open up.”
