The beauty mogul has taken to Twitter to call out an imposter who made a fake account using her old phone number.
She Tweeted: "the person who has my old number is pretending to be me... so anyone who had my [old number] beware. Feel free to give it a call."
This isn't the first time that the reality star has had her privacy invaded on social media.
Last year, her big bro Rob Kardashian leaked her phone number to Twitter after a bitter row between the estranged siblings.
Perhaps this is how someone got hold of her phone number to make the fake account?
Ugh, could the real Kylie Jenner pls stand up?
