Rumer Willis and her mother Demi Moore put on a united display at the Common Ground screening amid Bruce’s brutal struggle with dementia

Rumer Willis and Demi Moore put on a united display at a screening of Common Ground in Los Angeles on Monday.

Rumer, 35, is the eldest child of Demi, 61, and legendary actor Bruce Willis, 68.

Bruce’s family have had a very difficult year since his diagnosis of frontotemporal dementia, an uncommon form of the disease which causes a deterioration in behavior, personality and language.

But the mother and daughter duo appeared in good spirits for the screening, as Rumer looked radiant in a cosy jumper, while Demi was as age-defying as ever.

Rumer also posed for snaps with her boyfriend Derek Richard Thomas, with whom she welcomed her first child Louetta in April.

They were also joined by the Vampire Diaries’ Ian Somerhalder and his wife, Twilight’s Nikki Reed.

Common Ground is the sequel to documentary Kiss The Ground and joins celebrities in visiting farms all over the world, shedding light on the biodiversity of soil.

It features the likes of Ian Somerhalder, Jason Momoa and Laura Dern.

Meanwhile, Bruce’s family is said to be ‘soaking up every moment’ with the Die Hard actor while they still can.

A source told UsWeekly: ‘Bruce has good days and bad days, but in the last two months, there are many more bad days than good. This experience has brought the whole family even closer together.’

His wife Emma Heming Willis recently fought back tears while sharing an update on his health.

‘No one knows how much time Bruce has left, so they’re soaking up every moment they get with him. [Everything] revolves around him Bruce has around-the-clock care, but at least one family member is always with him.’

Bruce – who is married to model Emma, 45, but has daughters Rumer, 35, Scout, 32, and Tallulah, 29, with ex-wife Demi – became a grandfather for the first time when his eldest welcomed daughter Louetta in April.

Bruce and Emma also share two daughters: Mabel Ray, 11, and Evelyn Penn, eight. The couple married in 2009.

The iconic actor became a household name in a number of films including Pulp Fiction, Die Hard, Moonlighting, Armageddon, The Fifth Element, 12 Monkeys, Unbreakable, Tears of the Sun and many more.

Bruce’s condition – which causes issues with behaviour and language – was confirmed by his loved ones in a statement earlier this year which read: ‘As a family, we wanted to take this opportunity to thank you all for the outpouring of love and compassion for Bruce over the past 10 months.

‘Your generosity of spirit has been overwhelming, and we are tremendously grateful for it.

‘For your kindness, and because we know you love Bruce as much as we do, we wanted to give you an update.

‘Since we announced Bruce’s diagnosis of aphasia in spring 2022, Bruce’s condition has progressed and we now have a more specific diagnosis: frontotemporal dementia (known as FTD).

‘Unfortunately, challenges with communication are just one symptom of the disease Bruce faces. While this is painful, it is a relief to finally have a clear diagnosis.’
