People were talking about the MTV Video Music Awards, all right—and not just about the night's big winners.
The sweet moment quickly went viral as fans began speculating whether the two were more than just friends.
The 26-year-old Goulding, however, seemed far from amused by the chatter: Immediately afterward, she took to Twitter to set the record straight.
"I love that holding hands with my friends means we're an item," she wrote. "In that case I am in many relationships. Lover not a hater. #whatthef*ck"
Goulding's rep also told E! News: "They are just friends."
On Aug. 18, the two reportedly watched Kings Of Leon perform at the V Festival in Essex, England, and at one point, Horan supposedly leaned in for a kiss.
The duo were purportedly flanked by bodyguards, who helped shield the stars from onlookers' prying eyes.
A source tells E! News, though, that there is "no truth" to the romance rumors and that Goulding is still with her boyfriend, War Horse actor Jeremy Irvine.
"She and Niall are just friends," the source added.
Sheeran, for his part, seemed happy to put an eventful evening at the VMAs behind him, regardless of the chatter: Early Monday morning, he simply tweeted, "Bed."
