Rumer Willis discussed her mother Demi Moore s miscarriage and relationship with ex-husband Ashton Kutcher on an emotional episode of Red Table Talk Monday.

Willis, the oldest of her famous mothers three daughters, appeared on the talk show with Moore and sister Tallulah Willis. She told hosts Jada Pinkett Smith, Willow Smith and Adrienne Banfield-Jones why it was so hard to see her mother want to have kids again after raising her and her sisters with former husband Bruce Willis.

With Ashton, I was so angry because I felt like something that was mine had been taken away, Rumer confessed. When she wanted to have another baby and then it wasnt happening, and there was so much focus on that, it was like Oh, well were not enough.

But Rumer acknowledged she didnt quite understand the emotional pain of her mothers miscarriage until she stumbled onto pictures of Moore pregnant.

I think after you had a miscarriage, I literally was just like, Why are you so desperate to have another kid? I couldnt stand the idea, Rumer said to her mom. But then I found these pictures, and I was like, Oh my god.

She added that she saw how big her stomach was, and I was like, Oh my god, I was so insensitive. I never once went to you and said, Im so sorry, Are you okay?

Moore wrote about the miscarriage, which happened six months into her pregnancy, in her book, Inside Out. She also spoke out the experience with The New York Times , saying she had planned to name the baby girl Chaplin Ray.
