Watch out Beverly Hills, there's a new housewife in town.

Actress Lisa Rinna has reportedly signed on to join "The Real Housewives of Beverly Hills." Sources confirmed to E! News that the 51-year-old actress will join the cast of composed of Lisa Vanderpump, Brandi Glanville, Kyle Richards, Kim Richards and Yolanda Foster for the fifth season of the show, which will premiere in the fall.

The former "Melrose Place" and "Days of Our Lives" star will replace Joyce Giraud and Carlton Gebbia, who were fired from the Bravo reality series after only one season.

Rinna allegedly signed on to the popular show after a successful trial run during Kyle Richards' White Party in June, according to Radar Online.

The outspoken star was also reportedly a hit with the producers. However, the same can't be said for her new cast mates.

Rinna, who married former "L.A. Law" star Harry Hamlin, hasn't quite gelled with her new co-stars yet, insiders said.

"Lisa is getting along with many of the ladies, with the exception of Brandi [Glanville] and Yolanda Foster," a source told Radar Online. "Brandi's problem with Lisa is that she is happily married and has two beautiful daughters. According to Brandi, Lisa has the perfect life, and she is very jealous of that."

Glanville took to social media to set the records straight.

"Dear @radar_online ive met @lisarinna several times&she was lovely &I would never be anything but happy for people with great families!#fact," Glanville posted on her Twitter account.

In the past, Rinna has shot down rumors that she will join the franchise.

"Basically that was never gonna happen," the former "Celebrity Apprentice" star told E! News.
