One Direction's Harry Styles was celebrating his best mate Nick Grimshaw's birthday over the weekend, and who was he spotted with? None other than his ex-girlfriend Caroline Flack!
As well as Harry, there were heaps of other stars at the party including Kate Moss, Tulisa, Sadie Frost and of course Caroline Flack!

Nick Grimshaw is actually good friends with both Harry Styles and Caroline so things could have been pretty awkward, but it seems like they managed to be civil, as they partied together for a long time.
Harry emerged looking decidedly exhausted as he emerged in the early hours of the morning, and Caroline was quick to jump in a cab.
Do you think Harry would ever get back together with Caroline?
