Harry Styles has got back together with ex-girlfriend Paige Reifler.

The 'Best Song Ever' hitmaker is said to have reunited with his former lover after the pair were both seen at an exclusive party at Shoreditch House in London this week.

An insider told The Sun newspaper: ''Harry turned up specifically to meet up with Paige but they were as discreet as possible at the event.

''Then they both left the main party, which was on the rooftop next to the pool, and went downstairs to the more private restaurant. They were having drinks with her agents.

''But Harry ended up putting his arm around Paige and they were very flirty together. They ended up leaving on their own because there were lots of photographers outside.''

While the model is reportedly ''smitten'' with the One Direction pop star, it is said their respective careers mean a proper relationship ''might not'' be possible ''at this stage''.

The source added: ''Harry's been on 1D's world tour lately but it was good timing that he was around.

''Paige is completely smitten with him but realistic that their crazy lives mean it might not be able to develop into anything serious at this stage.''
