Rumer Willis shared a heartwarming glimpse into her father Bruce Willis's first Father's Day following his February dementia diagnosis. The actress posted a touching photo of Willis holding her newborn daughter, Louetta Isley, highlighting the special bond between grandfather and granddaughter.

In her caption, Rumer expressed her deep appreciation for the moment, describing Willis's love for Louetta as "pure and beautiful." She praised him as the "silliest, most loving, coolest Daddio" and the "Best Girl Dad in the game." Rumer also thanked her partner, Derek Richard, Louetta's father, for "building a beautiful garden" for their daughter and for being a fun and supportive parent.

Louetta is the first grandchild for Willis and his ex-wife, Demi Moore. The couple also shares two other daughters, Scout and Tallulah. Willis has two additional daughters, Mabel and Evelyn, with his current wife, Emma Heming Willis.

Rumer previously shared that her parents and sisters were thrilled about the arrival of the first grandchild. She also recounted the advice her parents gave her before Louetta's birth: "You have no control over anything, and just have a lot of grace with yourself."

The Willis family has shown unwavering support for Bruce since his dementia diagnosis, frequently sharing updates and heartwarming moments. Emma Heming Willis recently posted a video montage for Mabel's 11th birthday, showcasing Willis's close relationship with his daughter. She also shared a heartfelt tribute to Willis on his 68th birthday, acknowledging the emotional challenges of revisiting memories while expressing gratitude for the support she's received.
