Taylor Swift and Ed Sheeran have been best friends for over a decade.
The lyrical legends released their first song, "Everything Has Changed," together in 2012 and have been a part of each other's lives ever since, per UsWeekly.
"The A Team" hitmaker appeared on the Wednesday (April 9) episode of Call Her Daddy with host Alex Cooper and zoomed in on his longtime friendship with Swift.
"I see her when I see her. I probably see her, like, four times a year." Sheeran revealed that their most recent outings have been "proper sit-downs, six-hour catch-ups. I think that’s like a really nice way to do it."
The star joined the "Karma" songstress on tour the same year they released their first joint track. He noted that his favorite (and most frequent) memories with Swift were made during The Red Tour.
"I lived in Nashville, and she lived in Nashville. And we used to fly to and from the gigs together and do all sorts of [stuff]. I literally spent almost every single day with her for about six months."
The "Shape of You" standout recently looked back at messages he and Swift exchanged during the early days of their friendship and instantly felt "nostalgic."
"Going through all my old texts with people that I’ve known for that long, it was really, like, nostalgic."
