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.

Bruce Willis’ family celebrated him on Father’s Day, while acknowledging holidays can feel “hard” as he lives with dementia.

Bruce Willis was working with directors to continue acting before his diagnosis with frontotemporal dementia (FTD) was made public, his wife, Emma Heming Willis, reportedly claims in her forthcoming book.
