Demi Moore shares heartwarming video of Bruce Willis' family celebrating his 68th birthday following dementia diagnosis

• Bruce Willis celebrated his 68th birthday with family and friends on Sunday.

• His ex-wife Demi Moore shared a touching video of the party for the star.

• Willis was recently diagnosed with frontotemporal dementia.

It's been a difficult year for "Die Hard" star Bruce Willis after he was diagnosed with frontotemporal dementia, a condition that can affect a person's behavior, speech, and language. He retired from acting when he was originally diagnosed with aphasia in March 2022.

But Willis was in good spirits for his 68th birthday on Sunday, which he celebrated with his family at home.

The star was joined by his wife, Emma Heming Willis, and his ex-wife Demi Moore for the party — and Moore shared a heartwarming video of Willis singing along with their children before blowing out his birthday candles.

Moore wrote: "Happy birthday, BW! So glad we could celebrate you today. Love you and love our family. Thank you to everyone for the love and warm wishes - we all feel them."

Moore and Willis were married from 1987 to 2000 and had three daughters before separating in 1998, but they're clearly still close friends.
