Kylie Jenner has confessed to wearing Spanx.

The 'Keeping Up With The Kardashians' star has admitted she wears the control shapewear garments to give herself a curvier figure and bigger bottom.

A fan tweeted: ''Lmao Kylie just posted a picture on snapchat and you can see her butt pads (sic)''

And the 18-year-old star was quick to reply, telling her 12 million followers: ''They are spanx ... here's the link if u want some ;) (sic)''

The reality television star also revealed she is wearing waist trainers - made famous by her stepsister Kim Kardashian West - which 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. (sic)''

Meanwhile, Kylie was recently forced to deny she had breast implants, insisting she's just ''filled out''.

She wrote on her website: ''No, people - I haven't gotten breast implants! Everyone is obsessed with that. Truth is, as I've gotten older, I've gained 15 pounds and my body has changed; I've definitely filled out.

''I swear there are things you can do to work on problem areas without having to think about plastic surgery. Contouring has changed my life!''
