Ed Sheeran hangs out with Taylor Swift in Club Red during their concert in Detroit, Mich., on Saturday night (May 4).

“‘I Knew You Weren’t Trouble When You Walked In.’ She’s definitely a very good girl,” the 22-year-old British musician told Glamour about writing a song about Taylor, 23.

Ed also opened up about his favorite Ginger in the world right now: Prince Harry!

“He does it good because there isn’t a single woman on the planet that doesn’t want to marry a prince, and he just happens to be ginger. I personally don’t think ginger men have a habit of being attractive. We have to make ourselves seem attractive by doing stuff. I learned guitar, and he became a prince,” he added.

Ed is also pictured at the 2013 SunFest Music and Arts Festival on Friday night (May 3) in West Palm Beach, Fla.
