The musicians, who were briefly an item in 2014, reunited at the American Airlines Center in Dallas Tuesday. They performed at 106.1 KISS FM's Jingle Ball 2015, presented by Capital One. Goulding, 28, and Horan, 22, were all smiles while embracing and posing for a photo backstage. In addition to Goulding and One Direction, 5 Seconds of Summer, DNCE, Calvin Harris, Tove Lo, Demi Lovato, Shawn Mendes (with Camila Cabello), Charlie Puth and Zedd also took the stage.
The pop stars' reunion comes amid unconfirmed reports that Goulding and boyfriend Dougie Poynter are "taking a break." The Mirror reported Tuesday that the couple "hit a rough patch" because "their work commitments have meant they have been spending more and more time away from each other and it has made it difficult to maintain their relationship." Neither Goulding nor McFly's Poynter have commented on reports that they are "taking a break," however.
Which brings us back to Horan.
