Moore and Willis were married from 1987-2000, and are the parents of daughters Rumer, 33, Scout, 30, and Tallulah, 28.
Though divorced, they've remained tight, including traveling together.
Willis has moved on with wife (since 2009) Emma Heming Willis, with whom he is the parent of daughters Mabel, 9, and Evelyn, 7.
In 2021, Rumer Willis told People she is "so grateful" her parents are friendly coparents, saying, '"We have all really strived to have really deep and meaningful and honest communication. In any relationship — whether it's with a partner, whether it's with your family or your friends — that being honest and just really communicating well and having good tools for communication, I think, is so unbelievably important."
