Sara and Erin Foster have one thing they want to get off their chests -- don’t mess with their daddy!
While appearing on Jenny McCarthy’s SiriusXM radio show on Wednesday, the Barely Famous sisters said they believe their father, David Foster, has gotten a really bad rap after divorcing former Real Housewives of Beverly Hills star Yolanda Hadid.

"To be honest with you, our loyalty is to our dad, he’s a really good guy," Sara, 35, said Wednesday on Dirty, Sexy, Funny With Jenny McCarthy. "To watch him get dragged into some disgusting bullsh*t, Daily Mail, social media scandal -- all lies -- and for no one to come to his defense, it was unfortunate."
"Let me tell you something," Sara added. "[My dad] will give the shirt off his back to you, to you, to you. To anyone in this room."
Hadid, 52, had been married to Foster, 66, for four years when she filed for divorce in January. The former model has been open about her struggle with Lyme disease on social media and has documented her health crisis on Bravo's Real Housewives of Beverly Hills before exiting the show earlier this month.
"We don't comment to our friends on Yolanda’s health," Sara explained. "It’s not for us to comment on, only she knows her journey, 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."

"I know sick people," she continued. "I’ve been to Children’s Hospital. I’ve seen children who are f**king dying, so it’s not easy for me."
"We are not doctors, we have no idea what goes on, and we don’t wish anyone ill will of any kind," Erin, 33, said. "However, I think that from everyone’s experience, if anyone who has known someone who is very sick, who has cancer, who is in their last year of life, the only thing that person gives a sh*t about is getting through the day and being treated normally."
"No one wants everyone to know how sick they are and everyone to see how much they are struggling," she continued. "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."
Season two of Barely Famous premieres Wednesday at 10 pm ET on VH1.
The outspoken duo recently chatted with ET at L.A. Pride in the wake of the Orlando shooting massacre.
