Demi Moore Celebrates Grandmotherhood in a Leopard-Print String Bikini

Demi Moore was one of many celebs to hop onto Instagram over the weekend to celebrate Mother's Day—sharing a gorgeous black-and-white photo of herself wearing a string bikini and holding her grandchild, Louetta Isley Thomas Willis (aka Rumer Willis' daughter!). As Demi put it in the caption: "circle of life."

Rumer welcomed her first child with musician Derek Richard Thomas back on April 18—and they announced the birth in a sweet post on Instagram, writing "You are pure magic 🌱 Born at home on Tuesday April 18th. You are more than we ever dreamed of ✨"

Demi was by Rumer's side during the home birth, and Rumer shared pictures of the special moment during a Mother's Day tribute to her:

"To be able to celebrate this day with you is beyond words, the privilege to walk in this path of motherhood with you by my side to support and guide me is something I have only dreamed of. Thank you for holding the most beautiful space for me as I made the transition from maiden to mother. Thank you for helping me walk through and rise to the occasion to have the birth I dreamed of. What a gift to finally truly understand the depth of love that you have for me and my sisters because of my own endless well of love I have for my daughter. I love you mom. I am filled with so much joy and gratitude. I have never been so happy in my whole life. I have dreamed of this day since before i was born."
