David Foster’s daughters Sara and Erin both shared their thoughts over their father’s separation from Yolanda Hadid. The two actresses also weighed in on the former “Real Housewives of Beverly Hills” struggles with Lyme disease.

The sisters were very candid during their interview on Jenny McCarthy’s SiriusXM radio show on Wednesday. Both actresses defended their father David following the backlash that he received after his split from Yolanda, Entertainment Tonight reported. Sara described David as a “really good guy” and commented that their loyalty will always be to their father.

She then recounted the media backlash that the famous music producer has to endure after news of the former Hollywood couple’s divorce surfaced. David and Yolanda announced their divorce in January after four years of marriage. Sara stated that it was “unfortunate” that no one came forward to speak up against all the “lies.”

The “Barely Famous” star also made mention of Yolanda’s health challenges and explained that they were unable to comment on the TV personality’s struggles with Lyme disease. Although, she slammed her former step-mother for her participation in Bravo’s “Real Housewives of Beverly Hills” reality show. “But what I will say is, if you’re capable of continuing to be on a reality show, you’re not dying -- let’s be honest,” Sara stated.

Erin clarified that they “don’t wish anyone ill will of any kind” and shared that they were not expert medical professionals to fully understand what was going on. She mentioned that other people who may be going through a difficult health journey would typically focus on getting treatment and surviving the day-to-day challenges. The actress also stated that not everyone would want to see a sick person struggling through their disease. "And when that seems to be the focus, of making sure everyone sees how sick you are, that’s just confusing to someone that is trying to be supportive,” she added.

Meanwhile, Yolanda has announced her exit from the “Real Housewives of Beverly Hills” in an Instagram message posted mid-June, E!News reported. Bravo has also issued a statement to thank the reality star for sharing her story on the show. The network also stated that they respect Yolanda’s decision to “focus on health and family.”

Yolanda has been a part of the said reality show since its third season. In the sixth season of the series, the former model’s struggles with Lyme disease was featured on the show.
