"Dancing With The Stars" season 20 Rumer Willis and mother Demi Moore look identical in an Instagram photo posted on May 26, Tuesday. This was a week after Moore watched her daughter win the Mirror Ball trophy with her Val Chmerkovskiy on May 19.

"That moment when you realize you actually are becoming your mother #twinning#imnotmad," Willis captioned the photo, which quickly went viral.

In a recent interview with E! News, the "DWTS" season 20 winner explained just how the photo came to be. She said her mother had on this outfit and she thought it was really cute because they both "really like overalls and onesies."

"And she always, if I get a pair, two weeks later she's bought the same one," Willis explained. "So I asked her where she got it and she said, 'Oh, I actually have one that's a little bit bigger size upstairs and I put it on and then I kind of just look at us in the mirror and I said, 'We have to take a photo. Do you have another pair of glasses like this?"

On May 27, Wednesday, Willis was spotted in Los Angeles wearing a fringe jacket as she arrives back at the dance studio where she started rehearsals for the upcoming dance show "Sway, The Show," according to Just Jared.

Willis is set to reunited with Chmerkovskiy in "Sway, The Show," which will take place in New York City. She is also set to star in Will Slocombe's comedy film "The Escort" and Fouad Mikati's thriller "Return To Sender."
