In Billboard‘s story about the 20th anniversary of ‘N Sync’s debut album, the boy band members reveal that their rivalry with the Backstreet Boys was over a girl, not music. “I wanted to punch AJ [McLean’s] lights out for a little while. I was dating a girl, I broke up with her and he started dating her,” ‘N Sync member Chris Kirkpatrick recalls. “And I guess he was talking smack to her about me, so I confronted him on it and wanted to kick his a**.” He continues, “I don’t know how it got resolved–I saw him out one night and said I wanted to kill him, but I said, ‘Let’s get a beer.’ I think boy band fights are in the same realm as hockey fights. You fight when you’re on TV, but then when you’re not, you get a beer together. Now we’re really good friends.” Joey Fatone adds that when it came to music, there was “friendly competition” rather than a feud. “There’s nothing wrong with friendly competition–even though we are, of course, better than any of those boy bands. Maybe not right now, a little rusty,” he joked.
