“Dancing With The Stars" winner Rumer Willis shared a photo on Instagram of her and mother Demi Moore on Monday. The stars looked like identical twins rather than mother and daughter. “That moment when you realize you actually are becoming your mother,” Willis wrote with the hashtags “#twinning” and “#imnotmad.”

The picture showed the 26-year-old Willis and Moore, 52, with the same long, straight brunette hair, dark-rimmed glasses and navy jumpsuits. The only difference was that Moore had her hair center-parted, while Rumer’s was kept side-parted. The ladies had their hands tucked into the pockets of their silk onesies with a makeup-free look, according to Us Weekly.

The ageless mom was a constant presence in the audience as her daughter competed on the ABC dance competition. The star also shared the picture on Twitter, writing, “Bookends!!” And she took time out to remember last Monday, when she and partner Val Chemerinsky won the mirror ball trophy

Willis -- whose father is actor Bruce Willis -- wrote that it was the first Monday that she was not on "DWTS," dancing for the audience. But, she said that she was grateful for the amazing experience that she had on the dance reality show and the joy she got every week from dancing for all of the #teamvalenrue fans. Willis also shared some skimpy bikini pics, touting that “dance does a body good.” She was enjoying some Memorial Day sunshine by poolside.

In the picture, Willis is seen in a black two-piece bikini, flaunting her slim figure. One picture shows the star wearing a brown funky cat eye shade, with long, raven-colored hair left loose. The other picture shows the eldest of the Willis sisters from behind, standing near a pool.

Moore last month told Us Weekly how watching her daughter come out of her shell has been a wonderful experience. She said that all three of her daughters were bullied by the tabloids in their teens and it was very painful being a mom. She added that seeing her eldest daughter’s confidence grow has been a “thrilling” experience for her.
