Taylor Swift has written some mean songs about singers she's dated -- but she has nothing but love for her pal Ed Sheeran.

Taylor put pen to paper to share her feelings about Sheeran in Time magazine's 100 Most Influential People in the World issue, which hits newsstands today.

She writes,

"Whether by choice or an unconscious evolution, when he decided on his musical ambitions, Ed became less of a boy and more of a tank. He is protected by an impenetrable and ever-present armor of enthusiasm that has helped him endure any setback, letdown or underestimation. He’s like a fighter who pops back up on his feet before you even noticed he’d been knocked down."
