4. Reese Witherspoon And Ava Phillippe
Reese Witherspoon and her daughter Ava Phillippe (whom she shares with her ex-husband Ryan Phillippe) are practically twins — and we're not exaggerating. Mother and daughter look so much alike that they've been mistaken for each other.

"People come up to her [all the time]. We were at a premiere and they were congratulating her on her performance," Reese told E! News in 2017. "She's like, 'I'm not in the movie.'"

Awkward mixups aside, just take a moment to appreciate the twinning of Reese and Ava.
