Demi Moore and her three daughters sat down with Jada Pinkett Smith to candidly discuss how they overcame struggles in their family dynamic.

Rumer, 31, Scout, 28, and Tallulah, 25 -- whom Moore shares with ex-husband Bruce Willis -- reflected on what it was like to see their mother, 56, deal with addiction issues and ultimately relapse.

In a clip from Monday's episode of Red Table Talk on Facebook Watch -- which Pinkett Smith co-hosts with daughter Willow, 18, and mom Adrienne Banfield-Jones, 66 -- Tallulah said it was like "a monster came."

“I remember there’s just the anxiety that would come up in my body when I could sense that her eyes were shutting a little bit more, the way she was speaking. Or she would be a lot more affectionate with me if she wasn’t sober," she added.

“It was jarring,” Rumer said.

Tallulah continued: “It was very weird, and there were moments where it would get angry. I recall being very upset and kind of treating her like a child and speaking to her like a child. It was not the mom that we had grown up with.”

Moore went public with her sobriety issues in her tell-all memoir, "Inside Out."

Rumer has previously expressed admiration for her mother's openness. Earlier in October on “The Talk,” she said, “I’m so proud of her vulnerability, and I think so many women have watched her — and just as her daughter I’ve watched her — as this kind of beacon of strength and this kind of leader,"

She continued: “I think what I really respect about her is, she’s never the victim in her story. She takes accountability, she takes responsibility, and, mind you, this is her perspective, her story, and she’s the first one to say that.”

“She’s allowing herself to show everyone that you can go through some really difficult, hard things and you can still be someone who is thriving and taking accountability and just being a strong survivor without being like, ‘Oh, I survived this and this is who I am because of this story,’ which I think is amazing.”

Moore's issues with substance abuse started in her 20s when said landed a role on the soap opera “General Hospital.” She admitted she was in over her head and started using alcohol and later cocaine to cope with her fears, which caused blackouts.

“I don’t have an off switch,” recalled Moore. “I don’t have the thing that says, ‘This is enough.’”

Then in 1984, Moore earned the role of party girl Jules in the 1985 film “St. Elmo’s Fire.”

“I mean, I think the irony certainly was not lost on me,” said Moore.

Moore said she easily identified with her character and that the film’s producer and director insisted that she go to rehab. Moore committed to sobriety and her pledge lasted “almost 20 years” until she reached her 40s, when she relapsed.

“[It was] a profound gift that they gave me,” she said, speaking about sobriety.

Moore wrote in her book that the collapse of her marriage to Ashton Kutcher impacted her mental and physical health. The couple divorced in 2013.

She broke her 20-year sobriety and began abusing Vicodin and alcohol. Her three daughters stopped speaking to her.

Moore, who was in pain and isolated from her family, weighed a mere 102 lbs. In 2012, the Hollywood star was rushed to the hospital after smoking synthetic marijuana and inhaling nitrous oxide at a party.
