Season four of The Real Housewives of Beverly Hills has already begun taping with the return of Taylor Armstrong and Yolanda H. Foster, a source told RadarOnline.
Many questioned if Armstrong would return for the reality series' next season and the insider said "viewers just don't like her," but producers brought her back after having no luck finding a replacement for Adrienne Maloof and Camille Grammer.
Foster "is quickly become a fan favorite" and the "mama bear" on the Bravo series because she speaks up and addresses her co-stars when necessary, the source added.
Armstrong's return to the show was supported by Richards, whom reportedly campaigned to producers about bringing her friend.
"Kyle really wants Taylor to be asked back for the fourth season," an insider previously said. "She believes the producers owe it to [Armstrong] after the hell she went through in the run up to and after Russell's suicide. Tylor is really keen to come back too as the show is her only real source of income."
Lisa Vanderpump, Kyle Richards and Brandi Glanville are "all expected to begin filming this week," according to the source. Glanville's scenes, however, might be delayed because she is still recovering from laser treatment she had on her face.
Season four of RHOBH is expected to air this fall. It has not been confirmed by the network whether or not Marisa Zanuck will return to the show after starring in its third season. However, her "final blog entry" following airing of the season three finale episode hinted at her departure from the series.
A source close to actress Lisa Rinna said the former Days of Our Lives star is close to finalizing a deal to join the RHOBH cast for season four.
