Demi Moore, 61, stuns in tiny white bikini with granddaughter Louetta (2024)

Demi Mooreturned heads as she celebrated daughter Scout Willis' 33rd birthday during a family getaway over the weekend.

The Charlie's Angels star – who was in the front row of the Dior showin Paris recently – looked decades younger than her 61 years as she wore a tiny white bikini in a new Instagram post shared by her eldest daughter Rumer, 35, on Saturday.

She stood holding her 15-month-old granddaughter Louetta's hands as they walked on a dock together.

Demi accessorized her vacation look with a navy blue ball cap and Birkenstocks.

'River Monsters for @scoutlaruewillis birthday,' Rumerwrote in the caption of the post.

'No place I would rather be than by your side,' she continued. 'My leg bruise is courtesy of my first time trick riding on a horse woohoo.'

The toddler looked adorable in a long-sleeved pink swimsuit with darker pink zig zags and a polka dot bucket hat.

Demi's first and so far only grandchild looked delighted to have grandma helping her walk.

Rumer welcomed Louetta in April 2023 with partner Derek Thomas.

Rumer shared several more photos of the fun trip.

Another image showed Scout and youngest sister Tallulah, 30, enjoying a splash on floating water mat while rocking bikinis.

Rumer also shared a snap of her pert derrière in a lime one-piece swimsuit.

Scout's pal, Fred Houston, also posted an image and a video of her and a female friend enjoying the river on a foam mat and donning a colorful floral bikini.

Demi wrote a sweet message to the birthday girl on her Instagram, sharing four photos of her and writing, 'My sweet angel @scoutlaruewillis. Happy Happy Birthday! I am so privileged to be your mother and so grateful to be sharing this journey of life with you! The best is yet to come and I am so excited to see the magic that unfolds for you! I love you!'

One image showed Scout in a flowing white cotton dress standing in the center of stone ruins.

Another was a fresh-faced close-up of her, rocking a Halloween t-shirt.

There was also a snap of Scout doing a cartwheel in a lime top and tiny shorts, as well as a matching bucket hat.

The last photo showed Scout in a teal sweater and pink boots as she posed in front of a white background.

Scout also shared her own birthday post on Saturday, featuring a photo of herself with a lion head.

'I AM 33! IT'S MY BIRTHDAY! MY JESUS YEAR BEGINS! I AM SO HAPPY! I AM SO LUCKY! I FEEL SO GRATEFUL! I REALLY LIKE MYSELF AND I LOVE WHO I BECOME EVERY DAY! I LOVE MY LIFE! I FEEL SO INSPIRED AND THIS IS GOING TO BE THE BEST YEAR OF MY LIFE SO FAR!' she wrote in the caption.

Demi shares Rumer, Scout andTallulahwith ex-husband Bruce Willis, 69, who has been suffering from frontotemporal dementiasince around spring 2022.

In May, Rumer shared a rare health update about her father's battle with the rare and aggressive form of dementia.

Rumer suggested her father is in good spirits, telling the Today show simply, 'He's so good.'

She added that he remains a wonderful grandfather to her infant daughter Louetta, enjoys music, and spends quality time with his family.

However, while the family has not said it publicly, doctors tell DailyMail.com that the tragic reality is patients with Willis' condition are usually mute within just two to three years of a diagnosis.

FTD is different from the more well-known type of dementia, Alzheimer's disease. But unlike Alzheimer's, memory is not the first to go.

Aphasia - difficulty speaking and putting thoughts into words - is the first symptom for most. Willis has been struggling with this for two years.
