"I'm not like a big American football fan, but I've heard Drew Brees' name like a few times and he's quite known," One Direction's Zayn Malik admits about working with the star quarterback. "Like, whenever you mention him to everyone, everyone seems to know who he is ... He's a big deal."

For his part, Drew definitely knew of the British boy band, but wasn't quite confident in his singing abilities.

"Yeah, I got to sing with One Direction today but I can't say I had any musical aspirations growing up," he laughs. "Because I had zero talent in that department at a very early age."
