While appearing on Today with Jenna & Friends to discuss her new show Toxic in May, Chambers gave an update on how her family was doing overall.

"They're amazing. We're amazing. I think we've never been stronger as a family," Chambers explained. "This show touches on domestic violence, it touches on really unhealthy patterns. For me, I just experienced betrayal."
