The picture, which Wills, 26, posted online on Monday, May 25, shows the pair looking freakishly similar, wearing matching black jumpsuits and black-rimmed glasses, both with their long, dark hair in identical styles.
"That moment when you realize you actually are becoming your mother," the Dancing With the Stars season 20 winner captioned the photograph, adding the hashtags "#twinning" and "#imnotmad.
Not that Willis is complaining about taking after mom! The soul singer, who suffered from deep insecurities regarding her looks in her teens, has seen her confidence blossom in recent months as her climb to the DWTS top spot progressed.
Talking to Us Weekly last month, proud mom Moore, 52, told how watching her daughter come out of her shell has been a wonderful experience.
"The tabloid bullying all three of my children have experienced, especially in their teens, has truly been painful," the G.I. Jane actress shared with Us exclusively. "No child should be subjected to that type of judgment or criticism, especially based on their looks…As a parent, all you can do is love them and keep loving them until they love themselves."
Seeing Willis' confidence grow has been "thrilling!" she gushed to Us. "I am so proud of her and excited for people to be seeing what I have seen since she was a little girl. She is incredibly talented, and I love seeing her light shine!"
