Kimmy K, is that you?!

Kylie Jenner and boyfriend Tyga caught an early morning flight back to LA from NYC today, and we couldn't help but notice that the 18-year-old was totally jacking her older sister's signature look with her long grey duster coat, which she paired with baggy jeans and a crop top. The teenage social media queen has stolen Kim's glam squad and sense of fashion, and now it appears she's stolen a lot of the attention from Mrs. West as well!

The barely legal reality star was recently named one of Time's most influential teens, and while accepting the honor, she attempted to explain why her app is more popular than her more recognizable sibling's.

"Kim's older, she has a different fan base. The difference between our apps is [that] hers is very perfect. It’s simple, everything is black and white. I invite the cameras over and say, 'Oh, hey, let’s just do this.' We do makeup tutorials and I’m laughing and talking. I know my fans are my age or younger than me, so, I just like to show my personality and show my fans my home and my dogs. I get really personal. I’m on Snapchat, and I’m just like them at the end of the day. Kim’s more private. She has kids. It’s just different," she confessed.

She basically just called Kim old and irrelevant! Burn!
