Kylie Jenner launched a new app this week, and one of her first posts was a video titled "Kylie Comes Clean" that addressed those boob job rumors.

Since the 18-year-old confessed to having her lips done, people have speculated that she has had even more plastic surgery, especially when her chest started appearing much larger. 

In the new video, Kylie explains that her breasts are real, but she does use the help of a push-up bra, specifically the "Bombshell" from Victoria's Secret, to enhance her cleavage. To further prove her point, she posted before and after photos and the trick looks pretty legit.
