Not everyone would be happy about the fact that they look exactly like their mom, but when your mother is ageless Demi Moore, there’s not a lot to complain about.

Rumer Willis certainly wasn’t scowling about it in a pic she posted on Instagramon Monday.

“That moment when you realize you actually are becoming your mother #twinning #imnotmad,” she captioned the photo, which showed the 26-year-old and Moore, 52, with the same long, straight hair, dark-rimmed glasses and navy jumpsuits.

Moore – who was a constant presence in the audience as her daughter competed on Dancing with the Stars – also shared the pic on Twitter, writing, “Bookends!!”

And she took time out to remember last Monday, when she and partner Val Chmerkovskiy won the mirror ball trophy. 

“On this first Monday I am not on the #DWTS stage dancing for all of you I am filled with so much gratitude and love for the amazing experience I had and what joy I got every week from dancing for all of you#teamvalenrue fans,” she wrote. “Thank you again for helping me and @iamvalc share this moment. We couldn’t have done it without you.”
