Turns out one of Bravo’s “Real Housewives” is heading to “Chicago” — by way of Broadway — but it’s not New York City’s own Luann de Lesseps.

Erika Jayne Girardi — the self-proclaimed showgirl of “Real Housewives of Beverly Hills” — was confirmed Wednesday to take on the starring role of Roxie Hart in the longest-running American musical in Broadway history.

“I’m beyond excited to join the cast of the legendary musical ‘Chicago,’ ” Girardi, 48, told People. “Having been a fan of Bob Fosse and Gwen Verdon’s work it is an honor and a dream to play Roxie Hart.”

The eternal “Countess” Luann, 54, announced in July she was offered the supporting role of Matron “Mama” Morton in the classic musical, but negotiations fell through. Page Six reported at the time that she couldn’t swing the rehearsal schedule with shooting “RHONY,” booking cabaret gigs and maintaining her sobriety.

No word yet on whether it will be Girardi or her dance anthem diva alter ego “Erika Jayne” who will show up to play Roxie — the singing, dancing jailbird who craves fame like a, well, modern-day reality TV star.

What we do know: She begins her 12-week limited engagement with performances Jan. 6, 2020. (Girardi announced earlier this year that the upcoming 10th season of “RHOBH” would be her last so she won’t have to juggle both gigs for long.)

The blond bombshell is just the latest Bravolebrity connected to the iconic musical featuring music (“All That Jazz,” “Cell Block Tango” and many more) by John Kander and lyrics by Fred Ebb, with a book by Ebb and choreographer Bob Fosse.

Girardi’s “RHOBH” co-star Lisa Rinna, 56, starred as Roxie in 2007 opposite her husband, Harry Hamlin. And “Real Housewives of Atlanta” co-stars NeNe Leakes, 51, and Kandi Burrus, 43, both made their Broadway debuts in the scene-stealing jail matron role that de Lesseps missed out on.

The enduring production at the Ambassador Theatre is the winner of six 1997 Tony Awards, including Best Revival of a Musical and the Grammy Award for Best Musical Cast Recording.
