After the fourth season of The Real Housewives of Beverly Hills, Joyce Giraud and Carlton Gebbia were let go. In addition, many of the friendships among cast members were left in shambles. Richards and Vanderpump were on the outs, Vanderpump and Brandi Glanville were on the outs, but oddly, other friendships were forming, such as the one between Glanville and Kim Richards, who were previously at war.

"I think it's going to be our best season yet. It's a very complicated season," Foster, 50, explained. "I think a lot of things from last year… people are making up, new friendships, new people are coming into the group."

Before filming began on season five, Giraud and Gebbia were replaced by soap stars Lisa Rinna and Eileen Davidson.

"They're awesome," Foster said of her new co-stars. "I love both of them and I'm really excited to have two very intelligent, strong women that you know really make a difference in our group."

When Us Weekly asked Vanderpump if the wives were getting along, she said, "No."

The Real Housewives of Beverly Hlls is expected to return to Bravo for a fifth season later this year. Below, Lisa Vanderpump and other Real Housewives can be seen arriving to the 365 Style event.
