Is Cody a One Direction expert?

Cody Simpson sure knows his fair share about boy bands! He's close "mates" with The Wanted, has gone on tour with Big Time Rush- and has been forced to study up on One Direction? Yup, it's true! Cody's younger sister Alli is a huge fan of the British-Irish boy band and Cody admits that when it comes to chatting with his sister, he's had to brush up on his 1D knowledge. "I don't really know One Direction that well since they're from England," Cody tells J-14. "But [Alli] does! I don't really keep up with them but I have to go along with what Alli chooses, so I guess Harry Styles is my favorite member."
