Kylie Jenner is once again denying rumors that she's gotten breast implants.
But this time, the 18-year-old reality star is sharing her big secret to getting that ample cleavage look.
On her brand-new lifestyle website and app she launched today -- which costs $2.99 a month to subscribe to -- Kylie touts the wonders of Victoria's Secret Bombshell bra.
"I'm gonna share with you guys one of my tricks," Kylie says in a video. "I don't really share this with a lot of people, but everyone thinks I've gotten a breast augmentation recently. I haven't. I just use the Bombshell by Victoria's Secret."
"It's life-changing," she stresses. "I've gotten all my sisters on it, all my friends, and if you ever want the look of bigger breasts, that's what I do."
Kylie then shares what she looks like in a "normal lace bra" under a plain white tank-top.
... Which she compares to what she looks like when rocking the Bombshell bra.
"Clearly, it's like, 10 times bigger," Kylie proudly says about her cleavage. "No contouring, no nothing. This is, like, all padding here. I think it makes your breasts look great, and girly."
"This is it," she smiles. "No breast implants, no surgery ... it's amazing."
This isn't the first time Kylie has endorsed an eyebrow-raising product given her age. In July, a then-17-year-old Kylie Instagrammed a photo of her butt, claiming that she uses a cream to help enhance her derriere. "I love sharing my beauty secrets with you guys and this is a favorite!" she wrote, alleging that the product helps her "maintain and accentuate" her curves.
Monday's video also isn't the first time she's shot down breast implant rumors. In June, she caused plenty of heads to turn in a plunging dress she wore to the opening of a new Sugar Factory in Miami, Fla. "To whoever thinks I had breast implants, there's a whole lot of tape in here, holding these up," Kylie later explained in a Snapchat, before reaching inside her dress to show off her taped breasts.
Curiously though, Kylie is apparently all about the natural look when it comes to her makeup. "If I'm going to see people, I won’t wear heavy makeup. It's not attractive on me," she recently told The New York Times, but admitting that she still uses lip fillers.
