Taylor Swift And Harry Styles Reunited At NRJ Awards 2013 After Break-Up - Video
Both stars attended the French awards show and performed separately during the event.
The 'Live While We're Young' singers were named International Group/Duo Of The Year over the likes of Maroon 5 and Coldplay, and picked up their award in person wearing matching black and brown outfits.
The UK five-piece also performed their song 'Kiss You' live at the event, although the much rumoured reunion between Harry and 'Love Story' singer Taylor has not reportedly taken place.
The NRJ Awards in Cannes was believed to be the first time the former couple had seen each other since splitting at the start of the year, but the two walked the red carpet separately and have yet to comment on the split.
