Harry, 17, has confirmed that their split is by mutual agreement - and Caroline, 32, has always been realistic about the relationship, which started in October.
She received death threats and hate mail over their 15-year age gap, prompting her to ask Harry for space while she went to Goa at Christmas.
‘She confided that she doesn't think they'll last beyond the summer,' an insider revealed to Now last week.
'But she's just trying to enjoy herself. She does care deeply for him - he makes her laugh.'
It's claimed the One Direction star, 17, thought his romance with Caroline was getting too serious, but Harry insists this wasn't so.
