"Kylie realized she was getting a little bit too carried away with the treatments," the insider noted. "She's not going to give up entirely, but she's going to start the process of scaling back and undoing some of the things she's gotten."

The source claimed the Kylie Cosmetics founder, 27, is "starting to get some of her lip filler dissolved," adding that she wants to "reduce them to a more natural size."

"She's also talking about getting her butt downsized a little. She's wanting to be more high fashion these days and the extreme curves just don't fit the mold when it comes to the couture looks," the source continued. "She does love her big b-----, but a lot of people have suggested she should go down a few cup sizes if she wants to look more chic and less tacky."
