The 27-year-old singer had already announced his engagement in the New Year, to his childhood sweetheart Cherry Seaborn – but could it be that Ed sneaked this one past us?
The ring was first spotted a week ago by some of his Instagram followers, when a photo was shared of Sheeran recording in a studio.
“Wedding band on already? That was a short engagement!,” wrote one user.
And on Monda night, he was again spotted wearing it on his ring finger, while performing at the O2 as part of this year’s War Child BRITs Week.
Sheeran and Seaborn made the engagement announcement on social media, one month after the actual proposal.
“Got myself a fiancé just before new year,” he wrote.
“We are very happy and in love, and our cats are chuffed as well.”
Ed met Cherry when they were both students at Thomas Mills High School in Suffolk and the two finally began dating after he brought her as a plus one to a party at Taylor Swift’s house.
Sheeran’s one year hiatus in 2016 was used to travel the world with Seaborn, who was until then working in New York as a risk advisory consultant.
I’ve known Cherry since I was 11,” he told People magazine.
“She worked on Wall Street in New York, and I had like six shows. It was around then, and we reconnected. I went on tour again, and then I went to Taylor’s Fourth of July party.
“I was texting and she was like ‘I’m in Rhode Island at a 4th of July party’. And I was like ‘so am I.’
“I kinda said to Taylor ‘can I invite one of my old schoolmates?’ The rest is history.”
Sheeran has not responded to requests for comment.
