Reality TV star Kylie Jenner has confessed to wearing spanx.

The 18-year-old says she wears the control shapewear garments to give herself a curvier figure and bigger bottom, reports femalefirst.co.uk.

A fan tweeted: "Lmao Kylie just posted a picture on snapchat and you can see her b*tt pads."

Kylie was quick to reply, telling her 12 million followers: "They are spanx ... here's the link if u want some."

The `Keeping Up With The Kardashians` star also revealed she is wearing waist trainers, made famous by her stepsister Kim Kardashian. These are based on the traditional corset and aim to cinch in the waist, giving a more hourglass figure.

She tweeted: "Thanks @premadonna87 for keeping my waist snatched. http://Whatsawaist.com."
