Did Kylie Jenner get a boob job? Before and after Instagram photos have been causing a stir for months. And now new pics have sent the rumor mill into overdrive yet again.

The 19-year-old posted two photos on Dec. 20. The two pics show Kylie in a skintight maroon leopard print dress that puts her curves on full display. She captioned one of the pics with two smiley faces, hinting at the fact she was referring to her two ample assets. Within minutes the Internet was buzzing that the star had gone under the knife.

Of course, this isn’t the first time Kylie has faced boob job rumors. In August, the brunette beauty shocked fans when she took to social media showing off her large chest on Snapchat and Instagram. At the time, Kylie took to Twitter and denied getting plastic surgery. When one fan asked her when she got a boob job, Kylie replied, "Um never." She even told one fan that the reason her boobs were so big was because “it was that time of the month” and “they will deflate soon.”

In September, Kylie addressed the breast implant rumors again in a post on her website. "I don’t share this with a lot of people, but everyone thinks I’ve gotten breast augmentation recently, but I haven’t," Kylie wrote on her website in September. "I just use the Bombshell by Victoria’s Secret. It’s life-changing. I’ve gotten all my sisters on it and all my friends."

She added: "Clearly, it's like, 10 times bigger. No contouring, no nothing. This is, like, all padding here. I think it makes your breasts look great, and girly. This is it. No breast implants, no surgery ... it's amazing."

Kylie also had to deny boob job rumors last summer. In June 2015, she said on Snapchat, "To whoever thinks I had breast implants, there’s a whole lot of tape in there holding these up."
