Kylie Jenner shows off a lot of cleavage in these new photos added to her Snapchat account on Thursday, August 25, 2016. Something that a lot of the 19-year-old reality star's fans pointed out was that her breasts looked larger than normal and she took to Twitter to explain why. Kylie said that she has “never” gotten her breasts done and that they look large because “it's that time of the month”. She even offered to let a fan feel them to prove that they are real! “They will deflate soon. And it will be a sad sad day”, Kylie added. (Photo by Scope Features)
