The white fringed dress had a perilously low-cut neckline that showed off the curve of her breasts.
Fans then rushed to discuss whether the star’s chest has been surgically enhanced.
While one pointed out that Kylie’s figure is drastically different to how she looked dressed up as Christina Aguilera at Halloween last year. “Omg. So unfair how hot she is. Ok, look at her page from the Christina Aguilera costume and then to the sports bra pics after. Def had a boob job (sic),” the fan commented.
“She definitely has boob job done,” another fan agreed.
“As much as i love this girl.. she has definitely had work done,” a third fan wrote.
It’s not the first time that Kylie’s extra curvy figure has set the internet alight with rumours that she's had a boob job.
The brunette beauty may have been wearing a push-up bra, or she may be pushing her shoulders back and her boobs out.
But her fans were convinced she's had work done, and commented to let her know they were on to her.
