The 26-year-old posted this image of herself and her 52-year-old mother in matching outfits.

That moment when you realize you actually are becoming your mother #twinning #imnotmad

It's a moment that most of us dread: when you realize you're turning into your parent. But when that parent happens to be a famous movie star bombshell who looks the same as she did 20 years ago, it's probably easier to take.

That's how Rumer Willis, the daughter of Bruce Willis and Demi Moore, must have felt when she posted this Instagram pic of herself and her mother on Sunday. In their matching outfits, the resemblance between the two is uncanny. They even have their hair done the same way (good thing Rumer didn't copy her dad's style).
