Instead, Foster has been focused on raising awareness for Lyme disease, and sharing photos of her friends. Most recently, the mother of three shared a photo of Erika Girardi.

"Congratulations on an amazing and strong first season, your authenticity, kindness and loyalty shined bright #RHOBH #Reunion #TrueFriends @theprettymess," Foster captioned a photo of herself and Girardi last week.

On last night's episode of The Real Housewives of Beverly Hills, Lisa Rinna called out Foster for ditching their cast dinner at Erika Girardi's home in leiu of lunch with Kim Richards and Brandi Glanville.

“I felt that the other day I saw a picture with you, and Kim, and Brandi on the same day that Erika’s dinner was, and then you didn’t come to her dinner, and it got me,” Rinna explained, via Radar Online. “I didn’t understand why you would cancel that dinner and not come.”

“I have loyalty to Kim,” Foster said. “I don’t have to explain my friendships to anyone.”

Foster also said that Richards and Glanville had been bigger supporters of her throughout her battle with Lyme disease than any of the other women.
