Demi Moore defied nature when she flaunted her flawless body in a bikini alongside her daughters Tallulah and Scout Willis.

The trio got in some pool time when the girls was not able to hang out with their dad Bruce Willis on Father's day. They spent the day soaking up the sun with mom instead.

Tallulah posted the sexy snap on her Instagram account and captioned it: "When you can't be with the papa.... #freeslw #POOLPARTY #mymomsbodtho," giving her famous mom’s figure a shout-out.

Resting on one foot, Demi posed in her tiny red polka-dot bikini while she held her daughters gently in the shallows of the swimming pool.

Bruce Willis’ daughters looked equally as fit. Scout,23, chose a mix and match blue bikini, while the 21-year-old donned a chic one-shoulder white monokini.

Rumer Willis is noticeably absent from the photo op. She has been keeping busy with Dancing With the Stars' summer tour.

The 26-year-old even commemorated her success on the show by marking a victory tattoo on her forearm. Her new ink was a woman dancing with a shadowy-figured man made out of stars.

It was through the show that she had finally found confidence and learned to believe in herself after revealing that she had been bullied over her looks while growing up.

She opened up that her mom's beatiful looks affected her negatively. "I compared myself to her. I would go, 'My mom wears smaller jeans than me! Oh, God. Maybe I'm not skinny enough,'" she told Us Weekly.

"Every girl looks up to her mother, but my mom was larger-than-life and I felt I could never be like her," I just didn't feel like we were even the same caliber."

She added: "I'm really thankful that I had my sisters to lean on. They are my best friends."

Demi is known to being meticulous about her diet and she works hard to stay in tip-top shape.
