It looks like Kyle Jenner's ego and lips aren't the only thing that's inflated! We couldn't help but notice the teen looked bustier than usual earlier today.

Wearing a way too sexy uniform of crop top and skinnies, the 17 year-old showed off her larger-than-usual chest as she made her way into the family business office on Monday. Her curls, courtesy of Kylie Hair Kouture extensions, framed her formidable bust and narrow waist.

Is it just us -- or is Kylie a C-cup now? Watch out Kimmy K, you've got competition!

We'd say she seems to be enjoying her Christmas break, but the teen isn't on break -- every day's a holiday when you are home schooled! We've seen Kylie do a lot of things during the school week -- but we've never seen her with a book.

They say the children are our future -- if that's true -- we are screwed.
