Phillips encouraged this season’s cast to continue on their roads to recovery, as she said that "when we get well, our families get well."

Smith credited Uchitel with seeking help for her addiction to love, a fix she said is worse than pills.

“Love addiction is a killer -- I can’t stop,” Smith told Uchitel.
