Kendall Jenner flashes her bare butt and major underboob in tiny cut

KENDALL Jenner has shown off her curves in a steamy new swimwear shoot.

The 27-year-old model flashed her butt and underboob while posing in a series of tiny bikinis on Instagram for online fashion brand, FWRD.

Kendall displayed her cleavage while posing in the shower in a black cut-out bikini in one snap.

The Kardashians star slipped into a red one-shoulder thong bikini and posed on a bed in another racy image.

She almost risked a wardrobe malfunction as she pulled her bikini bottoms down.

Kendall, who is currently dating Bad Bunny, has been showing off her curves amid months of rumors that she's had a secret boob job.

Last year, Kendall sparked rumors that she had a breast augmentation.

In March, the TV personality was photographed looking fuller-chested than usual while on her way to visit 818 Tequila's bar at Revolve Social Club in Los Angeles.

Fans said it looked like she'd had a very natural-looking breast augmentation as she stepped out in a crop top and khaki skirt.

Last February, she was also accused of getting lip fillers like her sister Kylie Jenner, 25.

The Keeping Up With the Kardashians alum drew attention to her pout when she was photographed at the Super Bowl with her lips looking larger than ever.

In 2017, Kendall shut down plastic surgery speculation after fans claimed she'd had her lips done.

The model said in a blog post titled The Most Upsetting Rumor: "I was like, ‘This is CRAZY!’

"I didn't even address it at the time because if I address it people are going to be like, ‘Oh, so she's defending herself - she must be guilty.’"

She added in an Instagram Live: "As a model, why would I have my face reconstructed? It doesn't even make sense."

Additionally, her followers were recently convinced that she'd secretly had surgery on her butt.

She ignited speculation that she'd had work done while showing off her butt in a tight Dries Van Noten gown.

"Kendall, we know that ain't ya booty," one fan wrote on Reddit, while another added: "This is so cringe - like did u get a** injections Kendall?"

Some speculated that she has had Sculptra, which is a type of filler that stimulates collagen in the body over time.

It was originally designed for the face but is also a popular choice for those looking to have a non-surgical butt lift.

It aims to bulk up the appearance of the butt, create definition and the look of extra muscle mass.
