"I got rid of all my filler" she told a fan after she mentioned Jenner looked "like the old Kylie" in the snap.
The 20-year-old Keeping Up With The Kardashians superstar and business entrepreneur revealed the shocking news in a comment on her IG on Sunday (July 8).
For many years, she denied touching the stuff at all - despite the fact her lips were expanding at an exponential rate.
"She looks like the old Kylie here", one commenter wrote.
"I have temporary lip fillers, it's just an insecurity of mine and it's what I wanted to do", she said.
Moreover, Jenner's decision to have her cosmetic fillers dissolved might be a by-product of an overall new approach to her body confidence since welcoming Stormi in February. "I was 15 and I was insecure about my lips".
But Kylie was quick to respond to her devoted fans, writing: "i got rid of all my filler", with several anxious face emojis. "But I didn't lie".
Speaking about her biggest beauty blunder alongside her older half-sister Kim Kardashian, Kylie said: "Well, I definitely made my lips a little too big at one point".
"She has the most flawless lips in the entire world", the new mom said. "It was like one of my first kisses and a guy was like, 'I didn't think you would be a good kisser because you have such small lips'". However, he noted that Jenner could still keep her famous pucker if she got fillers just before becoming pregnant.
