See Demi Moore's Bright White Low Rise Bikini

Demi Moore wasn't going to let summer pass her by without appearing online in at least one seriously great bikini. The actress donned a two piece swimsuit during a getaway that featured both friends and family in honor of her daughter Scout Willis's birthday.

Moore was featured in a post on Rumer Willis's Instagram page. The first two moments in the carousel post saw a bikini clad Scout lounging in the water on a floating pad, and the second a photo of Rumer's cheeky backside in a neon thong swimsuit. The third image, meanwhile, featured Moore holding Rumer's daughter Louetta Isley while wearing a bright white bikini that sat low on her hips. Moore completed the look with a navy blue hat by Gap and black water shoes.

"River Monsters for @scoutlaruewillis birthday. 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," Rumer captioned the photo on her Instagram page.

Moore, meanwhile, made her own dedicated post to Scout on Instagram. "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 61-year-old captioned a series of images of her middle child. "The best is yet to come and I am so excited to see the magic that unfolds for you! I love you!"

This isn't the first time this year that Moore whipped out a bikini on the 'gram—she popped out in a leopard print string bikini on another vacation with her daughters back in May.
