Demi Moore posed in a bikini and looked flawless alongside her daughters Tallulah and Scout Willis in an Instagram photo on Sunday. The 52-year-old mother of three was pictured in a red, white and black polka dot bikini. Her iconic long hair was left loose, with a middle part, and she had on a pair of cat-eye sunglasses.

Moore is known for having one of the most enviable figures in Hollywood. She was flanked by Tallulah, 21, and Scout, 23. The picture was taken on Father’s Day as the daughters' caption read: “When you can't be with papa.” While their action star father Bruce Willis was in their thoughts, the main focus of the post was their mother.

The daughters looked equally fit. Tallulah donned a chic, white one-piece with her short hair pulled back to the side. Scout wore a teeny-weeny blue bikini, according to Us Weekly. Moore rested on one foot, as she posed in the shallow water of a swimming pool, her arms around her daughters’ shoulders. Her lean legs could be seen in the shot, as Tallulah rested her hand on her mom’s torso. Sister Rumer Willis, 26, was missing from the photo-op.

The “G.I. Jane” actress is fastidious about her diet and works hard to stay in shape. She credits a vegan diet and yoga for her slim body. In 2012, Moore told Harper’s Bazaar that she always has “had a love-hate relationship” with her body. Demi is very close to her daughters after a difficult few years following her divorce from Ashton Kutcher.

The actress recently returned to Twitter to rally support for Rumer, helping her to win on ABC's “Dancing With the Stars.” In a post afterward, the 26-year-old shared a picture of the mother-daughter duo, looking practically identical. Rumer joked that she was turning into Demi. They were pictured on Memorial Day wearing matching jumpsuits and glasses.
