Last time interviewed One Direction, the boys each revealed his favorite member of Big Time Rush. But this time, we turned the tables and had the guys from BTR spill on the 1D guy they heart most. Tough call, we know. Besides that, Logan, Carlos, Kendall and James dish on their current friendship status with the British-Irish boy band, what it was like touring with them, and who were the biggest pranksters of the group. See, we told you it was all about One Direction.
