The pop heart-throb, who at just 17 is 15 YEARS Caroline's junior, ditched her this week after deciding their relationship was getting too serious, much to the surprise of Caroline.

A source said: "It was never going to work and Harry knew that.

"The split happened very quickly after Harry made the decision to call it a day.

"He spoke to Caroline and explained that he thought it was best they break up. They've been spending a lot of time together so it's a blow to Caroline, who was serious about the relationship.

"After their romance became public it put a lot of pressure on young Harry.

"He'll be spending a lot of time in the US with the band this year so knows it will be hard to keep things on track."

And we didn’t really see that one coming, did we????????
