The 27-year-old announced his engagement to childhood friend Cherry Seaborn in January but has been tight-lipped ever since.
On the red carpet for the Brits in February, he told Sky News the ring on his wedding finger was his engagement ring.
But he appears to have suggested it has become a wedding band, pointing to it when asked if he had set a date for his big day.
In an interview with Access, he stayed silent when asked “have you picked a date?” – and raised his left hand instead.
The reporter said “that’s exciting”. Giggling, Sheeran replied: “Yeah.”
Asked how he had got away with it, the Shape Of You singer said: “I never do anything too public anyway.”
Sheeran announced his engagement to Ms Seaborn with an instagram post, saying: “Got myself a fiancee just before new year. We are very happy and in love, and our cats are chuffed as well xx.”
A year before, he had hinted that it was a serious relationship when he told Kiis FM in Australia that he was hoping to have children.
Sheeran went to school with his fiancee in Suffolk, but they didn’t become romantically involved until 2015.
