On March 3, 2016, Kylie used Snapchat to swap faces with her 35-year-old big sister, and they could be twins.
As seen on the 18-year-old's Instagram account for her Snapchats, there are a series of snaps of "The Keeping Up with the Kardashians" stars with their new faces.
In the first one, Kylie tells Kim, "I've always wanted to look like you."
And we hear Kim saying this is the "best face swap ever."
"I just think your face doesn't fit my head," Kylie tells Kim, and Kim agrees. "I always thought you had a really small face," Kim says.
While Kylie likes to be Kim, she's not so sure about Kim being her when they do a Kim and Kylie face mix.
"You don't look good, but that's my face," Kylie tells Kim in another snap.
Then there's this moment.
"Hey Kylie," Kylie says to Kim. Kim responds, "Hey Kim," back to Kylie, and it's tripping out their fans.
Instagram user @mxgha couldn't believe it. "This is so trippy. How is Kylie's face talking in Kim's voice and vice versa?" she questioned in the comments.
For Kim and Kylie, their similarities span more than just their looks.
In a September 2015 vlog titled "You're in Bed With Kim and Kylie," that was posted on Kylie's website, the topic of Kylie being a social media sensation just like her sister was addressed.
"How do you feel now that you have dethroned me?" Kim asked her in the video, but Kylie didn't comment.
"I mean honey, let's be real, you've got to put in a few more years before you actually dethrone me," Kim told her. "But I give my baton to you. Who better to pass on knowledge to my baby sister, rather than a random non-family member."
Kim further added, "You guys, this is amazing. I give Kylie all my tricks, I give her all my tips. I give her everything, and more."
And then she spoke about Kylie following in her footsteps.
"If I would want anyone to follow in my footsteps, anyone to borrow my clothes, anyone to like share my glam team it is Kylie, King Kylie," Kim said.
Now she's even shared her face!
