Diane Keaton’s mourning son, Duke, discovered a distinct method to honor her as he left her M five-bedroom ‘dream home’ in LA’s Sullivan Canyon on Sunday, just a day after her unexpected passing at the age of 79.

The 25-year-old nepo baby wore two crucifix necklaces with his all-black attire, similar to an eccentric look his famous mother pulled at the Hollywood premiere of Green Eggs and Ham in 2019.

Duke – who was mourning in all-black attire – works as a musician repped by 11:11 Records and he released his debut single Passenger Princes in August. 

Diane was 55 when she adopted the LA native in 2001, and she was 50 when she adopted her 29-year-old daughter Dexter in 1996.

‘They have no interest in what I do, which I think is very healthy,’ Keaton (born Hall) told People in 2007.

‘We live a relatively normal — well, sort of normal — life.’

Diane Keaton’s final moments have been revealed in a 911 call as friends say she was ‘very thin’ in the days leading to her shock passing at 79.

Further evidence of the sudden nature of Keaton’s death emerged Sunday with the release of the 911 call that was made to emergency responders.

The recording, obtained Sunday by TMZ, reveals a dispatcher calling for the LA Fire Department to respond to reports of a ‘person down’ at Keaton’s home address shortly after 8 a.m. on Saturday.

The Oscar-winning actress was transported to a nearby hospital where she was later pronounced dead.

songwriter Carole Bayer Sager told the Associated Press: ‘I saw her two or three weeks ago, and she was very thin. She had lost so much weight.’

Sager explained that Keaton had been affected by the wildfires that ravaged Los Angeles in January.

‘She had to go to Palm Springs because her house has been damaged inside and they had to clean everything.’

‘She was down there for a while, and when she came back , I was kind of stunned by how much weight she’d lost,’ the Grammy and Oscar award-winning lyricist shared.

Sager described her late friend as ‘a magic light for everyone.’

‘I just loved her,’ she said. ‘She was so special, she just lit up a room with her energy.’

Another of Keaton’s confidantes told People that the actress’ health fell off a cliff in recent months, something ‘which was heartbreaking for everyone who loved her.’

The insider added: ‘She declined very suddenly. It was so unexpected, especially for someone with such strength and spirit.’

‘In her final months, she was surrounded only by her closest family, who chose to keep things very private. Even longtime friends weren’t fully aware of what was happening.’
