Queen Bey has a solid strategy for email security.

“I have an email address I email [to get in touch with Beyoncé],” Sheeran told Entertainment Tonight of how his “Perfect” duet partner‘s email address “actually changes every week.”

Speaking with at KIIS-FM’s iHeartRadio Jingle Ball at the Forum in Inglewood, California, on Friday — where he took the stage with “End Game” collaborator Taylor Swift — Sheeran admitted that Beyoncé is incredibly good at “hiding” from the public. “It’s kind of what I aspire to be, I think,” he said.

Sheeran also revealed that their song had been planned since May and that they finished recording it in September. “The original version of ‘Perfect’ was just an acoustic guitar and she rung me up and was like, ‘I don’t know how you feel about this but I’ve taken all the instruments off it and it’s just gonna be acoustic guitar,’ and I was like, ‘Ah that’s great, because it used to be that!'” he said of the duo’s collaboration.

Here’s hoping that Sheeran will always have every update of Beyoncé’s email address.
