And she ain't too impressed.
Talking to Fabulous Magazine, Rebecca said 'I think there's something not right about Caroline and Harry's relationship.'
Rebecca, who dated Zayn when she was 24, continues: 'For me and Zayn it was different, because he was 18 so at least he could drive over to pick me up, we could go for a drink in a bar and he was old enough to make his own decisions.'
'But Harry's too young for that and there is so much more of an age gap between them.'
Tis true, there is 15 years between Harry, 17 (soon to be 18) and Caroline, 32, but we were thinking that surely Rebecca could understand their situation, considering there was 6 years between herself and Zayn. How wrong we were.
