Kylie Jenner appears to be experiencing immense augmentation in the chest area. She posted two new Instagram photos that have led many of her fans to posit that she recently went under the knife and came out as a more bountiful woman. Though the photos are of Kylie in a snug turtleneck, not showing any cleavage, the sheer volume of what's underneath is a sight to behold. Comparing the new photos to the cover of her 2017 calendar or to her Christina Aguilera costume from this year's Halloween, it seems that a transformation has indeed taken shape.

Now this is far from the first time Kylie has been accused of getting work done. In fact, she admitted to receiving lip injections when she was 17. And she even has already been accused of receiving breast implants this year. In August, she responded to fans speculating that her blossoming was artificial by blaming the enhancement on her period, writing, "TMI but it's that time of the month lol. They will deflate soon. And it will be a sad day." 

Also in August, she expressed that much of what her followers are witnessing is the result of her natural teenage development. "No, people -- I haven't gotten breast implants!" she wrote on her website. "Everyone is obsessed with that. Truth is, as I've gotten older, I've gained 15 pounds and my body has changed; I've definitely filled out." 

With the most recent size increase, the folks at MailOnline enlisted a professional to give his take on the situation. "Looking at the recent images of Kylie," said Mark Norfolk, the Clinical Director at Transform in the UK, "it would appear that she has had a recent Breast Augmentation." 

"Considering Kylie’s weight hasn’t fluctuated hugely over the last year it is unusual that her breast size would increase so dramatically," continued Norfolk, "and in my professional opinion, I don’t believe that this increase in size is down to hormones as she is claiming." 

So, who should we credit for the blessings Kylie has received this holiday season: Mother Nature or one of Hollywood's most skilled surgical artists?
