Rumours had circulated at the time of their break up that Zayn decided to end his four year relationship with Perrie over a text, but he was quick to shut them down and insisted he hadn't.
However, fans have now been left a little confused as Perrie has suggested Zayn did just that in a leaked excerpt of her new book with bandmates Little Mix.
According to Daily Mail, an excerpt detailing Perrie's reaction to her split with Zayn has surfaced on Twitter and in it, she writes: "It was horrible the worst time in my life. A four year relationship, a two year engagement ended by a simple text message. Just like that... it was incredibly difficult for me."
Perrie added: "The girls were amazing... I surrounded myself with friends and family. I didn't want to be alone because when I was, I'd start thinking about things and get upset."
She and Zayn had split in August 2015, with a source claiming to The Sun at the time: "He ended their engagement with one text message and in the two weeks since there's been complete radio silence between them."
Three months after news of their break up surfaced, Zayn addressed speculation surrounding his split with Perrie in an interview with Fader magazine. When asked if he had dumped her via a text message, Zayn responded: "I have more respect for Perrie than to end anything over text message. I love her a lot, and I always will, and I would never end our relationship over four years like that.
"She knows that, I know that, and the public should know that as well. I don't want to explain why or what I did, I just want the public to know I didn't do that."
Zayn hasn't responded to the leaked excerpt.
Perrie, meanwhile, added in the passage that she is "single" and in a "really good place." Having dealt with her engagement breaking down, Perrie reveals: "I feel like I'm stronger and happier than I've been in a long time."
She has since been linked to Our Girl star Luke Pasqualino and appearing to confirm their romance, Perrie recently revealed the pair have been out on a "few dates" together.
The 23-year-old told Daily Mail: "It's very early days. We're just seeing how things go really. We've been on a few fun dates, but that's all there is to it for now."
Zayn is currently in a relationship with supermodel Gigi Hadid. They first went public with their romance in December last year and made their red carpet debut as a couple at the Met Gala in May.
