The 18-year-old posted a Snapchat late on Monday night to show off her new pair of control pants but the conversation online, as it always tends to, soon turned cynical.
A number of fans commented accusing the reality star of wearing 'butt pads', which Kylie was quick to deny.
The starlet initially posted her snap, which shows her wearing only underpants and a loose vest, with the caption: 'These new spanx are bomb. From target'.
A fan was quick to comment: 'LMAO Kylie just posted a picture on snapchat and you can see her butt pads!'
Kylie, however, immediately responded to the jab by writing: 'They are Spanx…here's the link if you want some '.
