They remained tight-lipped about their brief romance, but Zayn finally opened up about their fling earlier this months, saying: "It was a wrong idea from the start. It shouldn't have happened. I think it was a wrong decision to make at such a young age. Then it did end badly so we don't talk any more."
Rebecca admits she's shocked by Zayn's brutal honesty, but insists she will take the high ground and keep schtum about their time together.
Speaking to New!, she said: "I was so shocked by what he said.
"I'm not going to retaliate. All I will say is that there have been a lot of things said and he knows so far that I've stayed classy and quiet and bitten my lip.
"I'm not one to reveal big secrets about what's gone on in a relationship, and I think he was probably put up to this. I know him too well to think he'd say it deliberately."
