The 17-year-old Kardashian star took to her Twitter page to warn fans against using shot glasses to make their lips swell up - in an alleged attempt to look like the teen.
The ‘challenge’ which became a trend on social media this week, involved Kylie fanatics sucking on shot glasses until their lips became red, swollen and sometimes bloody.
But Kylie was apparently horrified with the trend, taking to her Twitter to warn her fans off partaking in it.

‘I’m not here to try & encourage people/young girls to look like me or to think this is the way they should look’ she wrote.
‘I want to encourage people/young girls like me to be YOURSELF & not be afraid to experiment w your look.’
Kylie has come under fire in recent years for modifying her appearance significantly, with her lips especially seeming dramatically plumper.
But young people emulating her look could be risking ‘irreversible nerve damage’ if they try the lip challenge, Doctors have warned.
