Bruce Willis‘ daughter Tallulah has opened up about her father’s dementia battle after she shared a heartfelt post on Instagram on Wednesday.

Last year the Die Hard star withdrew from showbiz amid his battle with the brain condition ‘aphasia,’ which causes the patient’s language abilities to deteriorate.

And it has now been revealed that the 68-year-old is losing his ‘joie de vivre’ and ‘language skills’ after developing frontotemporal dementia (FTD) back in March.

Tallulah, 29, posted a selection of pictures of her and her father in the sweet snaps as she beams with her father’s arm around her as they cosy up together on a sofa chair.

‘Damn, these photos are hitting tonight’

The actress captioned the post: ‘Damn, these photos are hitting tonight. Youre my whole damn heart and I’m so proud to be your Tallulah Belle Bruce Willis.’

Tallulah also shared a picture of her driving license, revealing that ‘Bruce’ is also one of her middle names, giving her an even closer bond to her father.
