London Newspaper The Sun is reporting from a source that Taylor Swift and her longtime British boyfriend Joe Alwyn are engaged to be married.

While they have no plans to share the news publically, friends of the couple say that Joe bought the superstar a ring that she wears “behind closed doors.”

Recently, a source close to Joe said: “Taylor and Joe are incredibly happy and very, very in love. They’ve actually been engaged for a few months but have only told their inner-inner circle — basically immediate family and trusted, very old friends. Everyone has been sworn to secrecy, too.”

The source added, “Taylor has a beautiful ring, but she only wears it when she’s at home — i.e., behind closed doors. Again, only a handful of people know details about the wedding, and Taylor hasn’t even told some of her team about the engagement. Joe has been an absolute rock over these past couple of years. He’s obviously met Taylor’s family, and Andrea loves him. Similarly, Joe’s parents adore Taylor — she actually helped decorate his little brother’s bedroom.”

Swift reportedly divides her time between London and the family home in Nashville.
