Lisa Rinna (“The Real Housewives of Beverly Hills,” “Days of our Lives”) is about to get a taste of the Hecks when she guests on the third episode of ABC’s “The Middle,” which is entering its ninth and final season on ABC.

Rinna will portray Tammy Brooks, the “fun, charming and filthy rich mother” of Lexie (Daniela Bobadilla), Axl’s (Charlie McDermott) girlfriend and Sue’s (Eden Sher) best friend and roommate. The episode will be especially interesting when during the East Indy parents’ weekend Tammy and her husband Bennett meet Frankie (Patricia Heaton) and Mike (Neil Flynn) for the first time.

Entertainment Weekly first reported the news.

The ninth and final season of “The Middle” premieres Tuesday, October 9 at 8:00 p.m. ET/7:00 p.m. CT on ABC.
