Kylie Jenner has still not addressed boob job rumors, but the reality star nearly suffered a nip slip on Instagram thanks to her seemingly enhanced cleavage.

Wearing a black lace-up corset and high-waisted sweatpants, the 19-year-old almost had a wardrobe malfunction on the social media platform thanks to the low neckline.

Kylie has been sparking plastic surgery rumors recently thanks to her larger-than-ever chest, which she has been flaunting excessively on social media.

In the past, the lip kit mogul has denied going under the knife, even blaming her time of the month for her huge boobs.

“No ass implants,” she wrote on her blog, along with denying a nose job and breast implants. “You know, I used to be 120 [lbs.]. I told everyone, ‘I’m like I’m 120.’ I was like 16, I ride in my little G-Wagon. I was really skinny.”

She continued, “I’m pushing 136. But it’s alright I like the chunkiness.”

However, this wouldn’t be the first time Kylie has undergone a cosmetic procedure secretly. It took her months before she finally admitted to lip injections.

“I didn’t want people to think you had to get your lips done to feel good about yourself,” she told Complex magazine last year. “But they thought it was crazier that I was lying about it because it was so obvious. I wish I had just been honest and upfront.”

She also revealed her insecurity stemmed from an ex-boyfriend.

“This guy I kissed was like, ‘Your lips are really small but you’re a really good kisser. I didn’t think you were gonna be good at kissing.’ It was so rude,” she added. “From then on, I just felt like I saw guys staring at my lips. I felt like no one wanted to kiss me.”
