There’s a new star joining the cast of Bravo’s hit series “The Real Housewives of Beverly Hills” -- and her name if Erika Girardi. But by night, the blond-haired vixen, who is married to the “uber famous lawyer” Tom Girardi, is known as something entirely different: Erika Jayne, a chart-topping singer with a serious set of pipes and some major attitude.

“I have an alter ego,” the “RHOBH” newbie says in a clip from Season 6. “She’s sassy, she’s class and a--, and heels, and all woman all the time. She’s over-the-top fabulous.”

And apparently, she’s also over-the-top talented. According to Erika, she’s earned eight No. 1 hits on the Billboard dance club charts (“soon to be nine”) as well as traveled “all around the world” to perform her hip-shaking tunes like “Painkiller” and “Crazy feat. Maino.” But despite being well traveled, Erika dishes that she still has “a lot more dance floors to conquer” … starting with the dance floor in Beverly Hills.

During a Season 6 trailer for the sixth installment of “RHOBH,” Erika promises that she’s not “like your typical Beverly Hills woman who only eats salad.” Erika’s “RHOBH” co-star Yolanda Foster bolstered that statement when she describes the songstress as a “very colorful” woman.

“The body, the boobs, the lips, the hair,” she gushes over Erika’s stunning features. “But she’s [also] one smart cookie.”

Erika isn’t the only rookie joining Yolanda, Lisa Vanderpump, Kyle Richards, Lisa Rinni and Eileen Davidson during Season 6 of “RHOBH.” The California crew will also be welcoming former model Kathryn Edwards to the group.

“I haven’t seen Kathryn in a long time and I’ll tell you, after 20 years she looks exactly the same,” Kathryn’s longtime friend Lisa said, admitting her envy with a flick of her middle finger and a cuss.

“Real Housewives of Beverly Hills” airs Tuesdays at 9 p.m. EST on Bravo.
