During tonight's show, fans will watch as Foster addresses her recent split from husband David Foster and speaks of her illness.

Below is the synopsis for tonight's new episode, via Carter Matt:

“The gorgeous and glittering ladies of Beverly Hills meet with Andy Cohen for a gripping three-part reunion that begins with some fun insights into new housewife Erika Girardi, a.k.a. Erika Jayne. Kyle defends her friend Faye Resnick when Kathryn’s connection to the OJ Simpson trial is discussed, and Yolanda opens her heart about her pending divorce from David Foster. However, further conversation about her health becomes too much for Yolanda, leading to a surprising moment.”'

Last month, during an appearance on The Dr. Oz Show, Foster spoke of how her illness impacted her relationship with husband David.

"The patient suffers, but the caretakers suffer too. Because life doesn't only change for us, it changes for the person next to you," Foster said, according to a report by Us Weekly. "At the end of the day, David never changed, I changed. Unfortunately, these are the cards that life dealt me. It wasn't by choice. But I'm not the woman I used to be and I probably will never be again. My focus, my energy goes to trying to get well, trying to make a difference, trying to find a cure for my children … and David's life is really traveling, going to concerts, loud music. And I mean, I couldn't, I can barely listen to the radio."

The Real Housewives of Beverly Hills airs Tuesdays at 9 p.m. on Bravo.
