Speaking with Seventeen magazine for the upcoming April issue, the British songstress said she was never romantically involved with Sheeran despite their friendship.
"We've known each other for a few years," she said. "I think he's a really nice guy and a brilliant musician. We've bumped into each other and we've hung out and stuff, but the thing is if I hang out with someone, it's instantly like I'm 'dating' them. We were never in a relationship. My song is not about him."
Goulding also cleared up rumors she and One Direction member Niall Horan are an item. "We're still friends," she said. "We went on a few dates, and it was really fun. He's a really, really lovely guy. He's got the biggest sense of humor, he's very caring, and I see him as a genuine friend in the industry."
The singer recently made headlines when she announced she and photographer Conor McDonnell almost drowned in an icy Norwegian lake.
"Note to self don't drive a BV206 over a frozen lake," she wrote alongside a throwback photo of a car sinking in through the ice. The singer was in Norway ahead of her Delirium world tour.
