Happy Birthday, Kylie Jenner!

The youngest Kardashian turned 17 today and celebrated accordingly, complete with serenade by Justin Bieber! Big sister Kendall, Bieber, Chris Brown, The Game and Tyga were on hand for the party. There was even a penis cake!

From growing up on #KUWTK to making a statement with blue hair, Kylie has always kept us guessing. She may not be front and center like the rest of her sisters, but Kylie is the one to watch.

True to form, all of her sisters posted sweet messages on Instagram wishing their youngest sister a happy birthday. Momager Kris Jenner posted a sweet throwback and totally ’90s pic of her two babies, pouring her heart out to Kylie.

Wishing you the best birthday ever, Kylie!

Kim Kardashian GOES WITHOUT MAKEUP

We all know that Kim Kardashian has one of the best contoured faces on the planet, and loves to show it off via selfies. She even made a selfie book on her vacation to Thailand just for Kanye! I was floored when Kim posted a makeup-free selfie on her Instagram when she left the gym a few days ago.

Yes, believe it! This is a 100% makeup-free shot. No mascara, no lipstick, NOTHING. Those dark circles are out in full force, but Kim didn’t even use concealer.

It’s great to see Kim trying to switch things up, especially since North’s been born. Maybe Yeezus has suggested going sans makeup, or maybe she just doesn’t have the time for all of those products. Motherhood doesn’t always allow for time in front of the mirror.
