Calvin Harris met up with his frequent collaborator and ex-girlfriend Ellie Goulding at the GQ Men of the Year Awards in London on Tuesday. The DJ, who was honored with the trophy for best solo artist, hit the red carpet in a sharp black suit before being awarded on stage by Ellie herself. The pair, who have worked together on the hits "Outside" and "I Need Your Love," posed for photos together inside the event. It definitely had the potential to be an awkward night for Ellie; not only was Calvin in attendance, but so was her more recent ex, musician Dougie Poynter. Ellie seemed to laugh off the run-in and was all smiles while posing for photos with Dougie, whom she split from earlier this year. Clearly, Ellie could teach us a thing or two about staying on good terms with former flames. Another interesting connection that Calvin and Ellie share?...
