Yolanda Foster may not get along with every Real Housewives of Beverly Hills cast member, but the former model recently declared her favorite person on the show.

Lisa Vanderpump Gets Birthday Wishes From Brandi Glanville, Kyle Richards Despite Past Fights

On her Twitter account Wednesday, Foster revealed her favorite cast member from Real Housewives is actually Giggy! "A day in the office with my favorite cast member @giggythepom #RHOBH" Giggy is famously Lisa Vanderpump's furry friend.

Before, Foster also joined in the company of Brandi Glanville and Kyle Richards by wishing Vanderpump a happy birthday. She wished her (sometimes) friend health and happiness on her special day.

Richards also wished Vanderpump a happy birthday, telling her it should be "the best one yet" for the Villa Blanca owner.

Foster is back from her European trip with husband David Foster to shoot Real Housewives of Beverly Hills in Los Angeles. She is still wishing her daughter Gigi Hadid well though while the up-and-coming model took on London Fashion Week.

Hadid stormed the New York Fashion Week, as well, ending on a high note by walking in the famous Marc Jacobs show with other models like Kendall Jenner and Karlie Kloss.

"Gigi on the runway at NY Fashion Week 2014 for Marc Jacobs @MarcJacobsIntl #ProudMommy" Foster wrote on her Instagram account. Hadid is now back in NYC and Real Housewives of Beverly Hills is expected to come back this fall on Bravo.
