Watch Kylie Jenner's Total Transformation in 18 Photos

Kylie Jenner posted this adorable #tbt of Kendall Jenner as little babies. Could they be cuter?

Apparently, the answer is yes! So sweet.

Kylie has been attending events with her parents Kris and Bruce Jenner since she was just a little tot.

When Keeping Up with the Kardashians first premiered, Kylie Jenner was just 8 years old.

She didn't quite nail her red-carpet poses for a while.

The way they were! Kylie, Kendall, and brother Rob Kardashian look totally different these days.

Her hair is turquoise blue now, but Kylie Jenner experimented with pink first.

Somewhere in 2012 or so, Kylie Jenner became the queen of the selfie. She basically invented the term.

She posted photos almost daily that were zoomed in close to her giant, strikingly beautiful eyes.

She also raised eyebrows by uploading bikini selfies like this one, at the tender age of 15.

She definitely enjoys showing off her curves—she's related to Kim Kardashian, after all.

Look how fresh and preppy Kylie looked here! It's hard to imagine her rocking a look like this now.

Kylie actually looked just like big sister Kim at the 2013 MTV Movie Awards.

Like her sisters, Kylie Jenner loves experimenting with her hair, as seen with these temporary bangs.

She also tried out an ombre look.

Kylie Jenner has recently chopped her hair into a bob, with turquoise tips. She's also been loading on the make-up, with contouring and smoky eyes.

She's been focusing especially on big lips. Can't wait to see what you come up with next, Kylie.

Short hair no more! Kylie brought back her dark brunette hair color with a lot of length via extensions.
