In an interview with New! magazine, Rebecca opened up about why her three month romance with Zayn came to an abrupt end.
Rebecca and Zayn dated in 2011
"Zayn knows so far that I've stayed classy and quiet and bitten my lip," she said.
"I won't talk about what went wrong between us, but he knows what happened. And it is what it is. I won't expose what went on there."
But perhaps most revealing was her admission that she was 'yet to find a faithful man'.
She said: "I am a bit done with men. I am yet to find one faithful. I don't know why boys are like that. I think I am too nice with them and let them get away with murder. It is heartbreaking to feel that I have been let down like that."
Zayn was accused of cheating on Perrie with Australian waitress Courtney Webb when she sold her story to The Sun, claiming the singer had bedded her after a party at his home.
