Just last week, we could hardly tell the difference between Kylie Jenner and Kim Kardashian in a recent selfie — but now it's 19-year-old supermodel Kendall Jenner who's showing off her striking resemblance to her older sister!

In a Snapchat video posted to Kim's account, the 35-year-old stands beside Kendall as they both sing along to Kanye West's latest song, "Famous."

"Kendall & I had some fun last night, see it all on the snap!" she captioned the cute video.
