Earlier today, an Instagram photo that prominently features Kylie Jenner's cleavage created an unexpected uproar online.
Not since the now-deleted pic of Kylie's nipple piercing have fans expressed so much concern and confusion over the 17-year-old reality star's ever-changing figure.
But while online followers debate whether or not KJ has gone under the knife, at least one member of her inner circle reportedly has no doubt that she's had work done...and he wants her to stop flaunting it on social media.
"Bruce let Kylie have it after her saw the photo of her nipple ring posted," a source tells Radar Online. "He told her she is not an adult and needs to stop acting like some sex goddess."
Unfortunately, the insider says Bruce is on his own in his efforts to keep Kylie from growing up too fast:
"It is no secret that Kylie has had her boobs done. Kris will do anything to allow her daughters to be as plastic as she is."
"Kylie does not realize that the message she is sending out to her fans is that it is okay to change how you look and that plastic surgery is an option for everyone."
The source says Bruce has grown tired of Kylie's need for attention, and has made it clear that "he will not stand for it," even if it means butting heads with her mother.
Of course, it may be a case of too little, too late, as Kylie has been posting racy pics on Instagram for over a year and seems to have every intention of following in the footsteps of her sex tape-starring sister.
