Yolanda Foster appeared to explain why she remains close to Brandi Glanville in a tweet on Tuesday night.

Yolanda Foster Describes Being On 'Real Housewives of Beverly Hills'

During the latest episode of The Real Housewives of Beverly Hills, Glanville used Foster's daughter, Bella Hadid, as an example of how rumors can be untrue when talking about alcoholism. The comment came as an insult to Foster, and a shock to many others, which she seemingly led Foster to address her and Glanville's relationship online. 

"Those who are the hardest to LOVE need it the most #RHOBH," Foster wrote on Twitter as the episode aired.

In her confessional, Foster slammed Glanville for taking such a dig at her when she's always been supportive of her, but eventually the pair made amends, and have remained friends in the months since the scene was shot.

"To me, that was astounding," Lisa Vanderpump wrote of Glanville's comment in her blog. "There are no rumors of Bella being an alcoholic, of that I am sure. It was a hurtful statement which would've provoked a reaction I would not have been proud of, had it been leveled at my daughter."

"I ask myself as Yolanda states that she is lashing out, hitting below the belt, at what point is it enough?" Vanderpump asked. "At what point do you evaluate the pros and cons of your relationship? At what point, especially when it comes at your daughter's expense, can you say enough?"
