Before and after pictures of the reality star posted on Hollywood Life implies that she has gotten lip injections. Dr. Michael Salzhaur of Bal Harbour Plastic Surgery Associates also confirmed that the injections have made her lips triple the size they are before.

But Lyle M. Back, M.D. of Cherry Hills, N.J. said she might have overdone it.

"Unfortunately, she has that tell tale and not so natural 'duck lip' look going on. It looks like all the filler went into her upper lip - none in the lower. I like a little but more of a 'pout' in the lower lip. Her upper lip has been overfilled."

Dr. Yoel S. Shahar, a cosmetic plastic surgeon, also added that Bruce and Kris Jenner would have had to sign off on Kylie getting the injections considering she is under 18 years old. They added that lips might not have been the only body part Kylie surgically altered.

"When a person looks different it is usually a result from change in the shape of her upper lid and/or the shape of her eyebrow. Kylie has significantly higher eyebrow that can be created by surgery of brow lift (Botox can elevate eyebrows to much lesser degree 2-3 millimeter)."
