Ellie Goulding hit the stage at iHeartRadio and KISS FM's annual Jingle Ball in Dallas on Tuesday night. The concert brought out other hot performers like Demi Lovato, Tove Lo, and One Direction, and Ellie posed for a photo backstage with one of the band's members, Niall Horan. Niall and Ellie dated briefly back in 2013, and their romance was at the center of a much-talked-about love triangle with fellow British singer Ed Sheeran. Ellie was rumored to have hooked up with Niall while still dating Ed (and while the three were all staying in the same hotel). Earlier this year, Ellie set the record straight on the love triangle in an Elle UK interview, saying, "I did go on a few dates with Niall, but I was never in a relationship with Ed," adding, "I have absolutely no idea where that came from and why it was turned into such a big thing." Ed, however, all but confirmed that he and Ellie did have some sort of thing going, so we may never really know the truth.
The reunion with Niall comes at an especially interesting time, as it was recently reported that Ellie is currently on a break from her boyfriend, McFly's Dougie Poynter. Though the couple has yet to respond to any split rumors, Ellie has been staying busy promoting her latest album, Delirium, which features the song "On My Mind" — and is reportedly about her "maybe" fling with Ed.
