It's official: after months of speculation, Kyle Richards and Yolanda Foster have confirmed they are returning to Real Housewives of Beverly Hills for Season 5.

Was Kim Richards Spotted Kissing A Mystery Man In Los Angeles?

"Yes, [we'll] be back," Richards told In Touch Weekly this week. "I'm ready to go back."

Foster also confirmed her return to the hit Bravo show. "We began filming [the new season] a few days ago," Foster said, adding she's sure there will be some drama during the new season. "It'll be great. Things always start off slow in the beginning."

Are Lisa Vanderpump And Kyle Richards Friends Again?

Lisa Vanderpump just confirmed her return to the show on Twitter. On June 20, Vanderpump wrote, "Well ok...Five has always been my lucky number,so we will see. #rhobh Let the games begin."

Carlton Gebbia and Joyce Giraud were let go after one season on the show. Joining Vanderpump, Richards and Foster are other Beverly Hills ladies Brandi Glanville and Kim Richards.

One person not joining the cast despite rumors appears to be actress Suzanne Somers. Somers "may have filmed or is going to film scenes in a social setting, but she is not joining the cast," a source told E! News. A rep for Somers also denied the Real Housewives rumors. "We do not have any comment, since no one has contacted Suzanne about these talks."

Although Somers made an appearance on the reality TV show, the actress said she most likely would not be up for all the drama. Somers told Access Hollywood, "That's not in my nature, I don't fight."
