Harry Styles Birthday: One Directioner Celebrates 19th With Ex Caroline Flack (PICS)

Harry's Unlikely Party Guest

Long before there was a whiff of Taylor Swift, Harry Styles dated Caroline Flack (remember that?).

And as the One Directioner celebrated his 19th birthday with a night on the town on Thursday, Flacko was one of his many celeb pals who joined in with the fun at London's Groucho club.

We wonder what Taylor has to say about that?

Proving they were still on good terms, the exes spent the evening together at the trendy club along with the likes of Nick Grimshaw, James Corden and model Cara Delevigne, who denied ever dating Harry earlier this week.

But his One Direction bandmates were notable absentees as they were nowhere to be seen when the group headed home in the early hours.

Needless to say Harry's other ex Taylor Swift was not in attendance either, as despite rumours of a reconciliation, the pair are now said to want nothing to do with each other.

Guess they really are never, ever, ever getting back together then...
