Ed Sheeran first confirmed that he and his longtime girlfriend Cherry Seaborn were married.
British media reported that twins were married before Christmas in front of their family of about 40 friends and family in Suffolk.
Sheeran told Charlamagne Tha God that he would write his "Remember the Name" song "My Wife" in an interview with Broadcaster Charlamagne Tha God to promote his album No.6 Collaborations Project.
The 28-year-old British composer said, "We knew we would get married when the song came out."
The album released on Friday includes collaborations with Justin Bieber, Stormzy, Eminem, 50 Cent and Bruno Mars.
Sheeran and Seaborn (age 26) met at an elementary school in eastern England and announced the fight in 2018.
