Demi Moore looks more like her daughter Rumer Willis' identical sister than her mom in a new Instagram photo.

The 26-year-old Willis posted a pic of her wearing the same outfit as her 52-year-old mom and the two women look like twins.

"That moment when you realize you actually are becoming your mother #twinning #imnotmad," the oldest daughter of Moore and Bruce Willis captioned the photo. She shouldn't be mad! Her mom looks incredible. Willis credited her championship run on "Dancing with the Stars" for her own stellar physique that she showed off in another Instagram pic, this time clad in just a black bikini. "Dance does a #body good. Real good," she wrote on Memorial Day.
