The couple married in 1987 and separated in 1998 before filing for divorce in 2000. Bruce Willis and Demi Moore have three daughters together: Rumer, 34, Scout, 31, and Tallulah Willis, 29.

With Emma Heming Willis, the actor had two more daughters, Mabel, 10, and Evelyn, 8.

His younger daughter Scout posted the same video as her mother Demi, along with a photo of her as a child sitting on her father's shoulders and appearing to sleep.

An image captioned with the text: “One of my best friends, the Pisces King, the master of duality, both an action hero icon and a kind dad”, adding that it was “a privilege” to have him as a father.

Bruce Willis was diagnosed last month with a form of dementia called frontotemporal dementia.

This diagnosis comes about a year after the revelation of his fight against aphasia, which led him to move away from the acting profession.

“Although it is painful, it is a relief to finally have a clear diagnosis,” his family had said in a statement shared on the Association for Frontotemporal Degeneration website.
