Zayn Malik reportedly cheated on his girlfriend, Perrie Edwards, with Australian waitress Courtney Webb.
Courtney's former friend (and a current friend of Zayn's), Leon Anderson, announced Courtney's mobile phone number on Twitter, and in the space of a few hours, she'd begun to receive death threats from around the world.
Says Courtney: "I was expecting some abuse but it has got out of control. I’ve had hundreds of calls from all over the world. One American girl left me six voicemails in an hour saying she was going to kill me. It’s really scary."
Leon has since deleted the tweet.
Meanwhile, Perrie is saying she's "totally fine" and not getting over-involved in the drama.
