Demi Moore Rumer Willis Twinning(Photo: Instagram/RueLaRue)

Rumer Willis shared a photo yesterday on Instagram that proved she was becoming her mom Demi Moore. They looked identical wearing matching navy jumpsuits, thick black glasses and they both wore their long dark hair down. This was #twinning. Most celebrity daughters are spitting images of their famous mothers, but sometimes they post photos like this that make us realize they are even more similar than we thought.

Here are 8 celebrity mother-daughter twinning photos:

You can definitely see some on dad Ryan Phillippe in daughter Ava, but she has the exact same smile as mother Reese Witherspoon in this photo. They don’t even need to be wearing matching lipstick or have the same hair color to see that.

2. Christie Brinkley And Sailor Brinkley CookChristie Brinkley And Sailor

Christie Brinkley and her teenage daughter Sailor Brinkley Cook manage to look like sisters in a lot of their photos, so it’s not that surprising that there are a lot twinning photos on their feeds. This pouty selfie is just one example.

What would a mother-daughter list be without Goldie Hawn and Kate Hudson? These two seem so similar from their blonde hair to the fun-loving personalities. They manage to look like twins in random photos such as this one at Fashion Week. They are wearing coordinating black dresses and heels and have the same cocked head and cheeky grins.

This is a throwback #twinning photo of Julianne Moore and her daughter Liv Helen from a few years ago. Look beyond the stunning red hair and you’ll notice that have similar one-shoulder-in-front-of-the-other poses.

Random twin photos are the best. It is doubtful that Katie Holmes and daughter Suri Cruise planned this photo just to please us and the paparazzi. However, we all know those coordinating pink outfits were definitely intentional.

6. Nicole Richie And Harlow MaddenNicole Richie Dalmatian Halloween

Coordinating family Halloween costumes may not count as a proper #twinning photo in some people’s books, but it is too cute not to include. Nicole Richie, daughter Harlow Madden and son Sparrow dressed up as the “101 Maddens.” Awww.

7. Kim Kardashian And North Westkim and north

In some photos it is obvious that North West takes after her father, but this set shows she definitely has some Kardashian blood in her. North and Kim Kardashian have the same serious paparazzi face, except North’s doesn’t have any contouring.

8. Gillian Anderson And Piper Maru Klotzgillian-anderson-and-daughter-2

Here’s a red carpet #twinning moment courtesy of Gillian Anderson and her gorgeous daughter Piper Maru Klotz. You have to wonder whether they practiced posing like this in front of the mirror together or whether this identical pose and facial expression is down to good ol’ fashioned genetics.
