Kylie Jenner Looks Like She Got a Boob Job

Kylie Jenner is either pulling a Pamela Anderson, or the camera that took this shot adds a few pounds ... to her chest.

Kylie posted the shot on the left on Tuesday, and if you compare it to one she took at Halloween -- in her Christina Aguilera costume -- it sure seems like there's been some kind of enhancement.

Could be padding, the angle or even surgery -- but there's no getting around 'em ... those puppies are larger and in charger.
