Lauren Richardson, 26, was catapulted into the limelight in March after photographers snapped her and Zayn looking cosy outside a nightclub in Phuket.
Zayn was forced to issue a public declaration of love to Little Mix fiancée Perrie Edwards. A few days later, he quit One Direction.
Speaking to The Sun, community sports officer Lauren said: "There were death threats and people saying they would find me. There was a lot of hate behind everything. I was scared."
She added to Daily Star: "Fans were saying to me, 'It's your fault, we are gonna get you' and: 'We hate you'. Every picture I put up, I still get: 'You're a bitch you're a sl*t, you're ugly.' Even now. And they don't even know me."
Lauren said that nothing happened between her in Zayn: she claimed she asked him for a photo inside the club after learning 1D were partying there during a break on their world tour.
It was just an innocent picture. Nothing else happened. He is a handsome lad but it is not something I would dive into it."
Lauren will have the chance to tell her side of the story on ITV2's Love Island. She's one of the contestants on the revamped show, which begins this Sunday at 9pm.
