In it, Kylie, 26, stared seductively at the camera, donning a black bra and matching leggings with her long dark hair in an updo.

The close-up shot captured her toned arms and bare stomach, despite the reality star previously convincing fans that she is expecting her third child.

Kylie – who is already a mom to a daughter, Stormi, five, and a son, Aire, one, with her ex, Travis Scott, 32 – raised fans’ eyebrows last week when she posted a snap of what looked like her sporting a baby bump.

Initially posted by Kylie’s friend, Lauren Perez, the pic was shared to her Stories, showing a woman sporting a red sweat outfit and a white crop top, exposing her seemingly pregnant belly.

Lauren tagged Kylie and the Hulu star’s new clothing brand, Khy by Kylie Jenner.

While the reshared photo was clearly not of Kylie, many thought it was the Keeping Up With the Kardashians alum at first glance.

“When I first saw this on Kylie’s Story I thought it was Kylie revealing a baby bump and promoting Khy. I had to do a double take,” one social media user wrote on a popular online forum.

Others even thought the snap was Kylie’s older sister Kendall, 28, who has also been at the  center of pregnancy rumors with her boyfriend, Bad Bunny, 29.

Meanwhile, Kylie’s romance with actor Timothee Chalamet, 27, has been heating up, leading many to think the idea of her being pregnant wasn’t very farfetched.

The couple went public with their relationship earlier this year, and Kylie has been seen supporting her man during his recent appearances.

Chatter first circulated that Kylie was expecting in November when she accepted her Wall Street Journal Magazine Innovator Award.

The Kylie Cosmetics founder wore a dark brown dress to the event, and many noticed the star cradling her stomach throughout the night.

“Kylie cradling her stomach- lil Timothee?” someone commented on another online thread.

ALREADY OVER?

However, others have speculated that Kylie and Timothee might have called it quits after they recently spotted a suspicious detail on her phone.

Fans got a closer look at Kylie’s phone when photos captured her leaving a Los Angeles, California restaurant with her mother, Kris, 68, and sister Khloe Kardashian, 39.

Upon closer inspection, the phone’s background was a pic of Kylie’s kids instead of a photo of Kylie and Timothee, which she had at the beginning of their relationship.

The former snap was of the New York native kissing Kylie on the cheek.
