Demi Moore Rocks Tiny White Bikini on Daughter's Birthday Outing

Demi Moore joined her daughters Rumer, Scout, and Tallulah Willis for a river getaway while celebrating her middle daughter's 33rd birthday over the weekend. The 61-year-old could be seen rocking youthful figure in a tiny white bikini while standing over her one-year-old granddaughter Louetta, whom Rumer gave birth to last April.

"River Monsters for [Scout Larue Willis'] birthday," Rumer captioned the series of photos on Instagram, jokingly referring to the long-running Animal Planet wildlife documentary series. "No place I would rather be than by your side. My leg bruise is courtesy of my first time trick riding on a horse woohoo."

In the photos, the 35-year-old could likewise be seen bearing her derriere in a high-cut, bright yellow one-piece swimsuit, while Scout opted for a yellow string bikini. Moore's youngest daughter, Tallulah, 30, likewise appeared next to Scout in one of the photos wearing a dark-colored bikini.

This isn't the first time this year the famous three sisters have flaunted their bikini bodies on social media. Back in April, the adult daughters of Bruce Willis (who also shares two daughters, Mabel, 12, and Evelyn, 9, with his current wife Emma Heming Willis) appeared in another social media post wearing matching pink swimsuits along with the toddler, who was likewise clad in pink.

"On Wednesdays We Wear Pink, [featuring] the littlest Willis" Rumer captioned the post, referring to the popular 2004 comedy Mean Girls. During that outing, however, neither their mother, nor father—who has been battling frontotemporal dementia in recent years—joined in on the fun.

Since Willis was first diagnosed with the cognitive impairment aphasia in 2022, his family, including Moore, have put together a united front in supporting the patriarch.
