Rumer Willis gave an update on her father Bruce Willis’ battle with dementia in a heart-wrenching Father’s Day tribute.

“Today is hard, I feel a deep ache in my chest to talk to you and tell you everything I’m doing and what’s going on in my life,” she wrote via Instagram Sunday.

“To hug you and ask you about life and your stories and struggles and successes. I wish I asked you more questions while you could still tell me about it all,” Rumer continued, suggesting he was having trouble with his speech and memory.

“But I know you wouldn’t want me to be sad today so I’ll try to just be grateful reminding myself how lucky I am that you’re my dad and that you’re still with me,” she added.

“I can still hold you and hug you and kiss your cheek and rub your head I can tell you stories.”

The 36-year-old actress gushed over how the “Die Hard” star’s ”eyes light up” when he sees her 2-year-old daughter, Louetta, whom she shares with her ex Derek Richard Thomas.

“I will be grateful for every moment I have with you. I love you so much dad happy Father’s Day,” she continued.

“Sending love to all those who are in the boat with me or have lost their fathers, to the single moms who are the dads too, to my future baby daddy…❤️.”

Rumer shared a series of photos of herself and Bruce throughout the years, plus one of her father with his granddaughter.

Bruce, 70, stepped out of the spotlight in 2022 after being diagnosed with aphasia.

In 2023, his family revealed he was battling frontotemporal dementia, which results in speech and behavioral issues, per the Mayo Clinic.

The actor shares Rumer, along with daughters Scout Willis, 33, and Tallulah Willis, 31, with his ex-wife, Demi Moore, whom he was married to from 1987 to 2000.

The exes have maintained an amicable relationship throughout the years, and the “Substance” star, 62, has visited Bruce every week amid his ongoing health journey.

Bruce also shares 12-year-old daughter Mabel and 10-year-old daughter Evelyn with his wife, Emma Heming, 46.

Heming, who married the “Pulp Fiction” star in 2009, often gives updates on her famous husband and the “monumental highs and devastating lows” of his health battle.
