Rumer Willis & Mom Demi Moore 'Twinning' on Instagram Pic: 'DWTS' Winner Reveals Bikini Fitness Secrets

Rumer Willis, 26, could pass as her celebrity mom Demi Moore's twin in a picture she recently posted on Instagram. Both mother and daughter are in the picture, particuarly Rumer, who recently won Season 20 of "Dancing With the Stars."

According to Perez Hilton, Rumer posted a picture of herself standing next to her famous mother on Instagram. Interestingly, the snap shows how the pair look like mirror images of each other.

In the photo, Rumer and Demi Moore rock the same jumpsuit and glasses. The mother-daughter duo even style their hair the same way. Rumer captioned the snap: "That moment when you realize you actually are becoming your mother #twinning #imnotmad."

Bruce Willis' daughter looked great beside her mother, and she has her training with "DWTS" to thank for. The 26-year-old participated in the Season 20 of the popular dance competition and she emerged victorious, winning the golden mirror ball trophy.

All of her hard work on the show did not just make her a winner, but also gave her a toned body that rivals her mother's. According to Daily Mail, Rumer recently showed her perfect physique this past Memorial Weekend. She was seen wearing a floral bikini while playing football.

Rumer credits her intense training and practice sessions on "DWTS" for her toned arms and legs, as well as her flat tummy, reports Celebrity Health Fitness. "It definitely changes your body a lot," she said. "Everything getting a little bit tighter."

Rumer also does yoga with her mother, and this could probably be her post-"DWTS" routine to maintain her fit body.

Rumer told People in the past that she is not a big fan of hitting the gym. She also shared her diet plan at the time.

"I don't really eat dairy, no gluten, and I don't really eat red meat," she said. "It's half of the reason why I'm in the shape I am."

She added that her diet usually consists of chicken, leafy greens, and avocados. Besides all the healthy foods, Rumer admitted that she, too, allows herself some unhealthy indulgences.

Rumer's food weaknesses are sweets and French fries. "I have a gnarly sweet tooth and I eat alot of Haribo gummy bears. It's my thing," she gushed.

She also shared, "French fries are my guilty pleasure. I'm such a snob for fries - [I] hunt and search for all the best fries places ever!"
