The year 2012 was One Direction's biggest to date: They released a debut and a sophomore album within six months of one another, toured the world, went multiplatinum, dated superstars -- it's good to be the kings of boy bands! But one moment stuck out more than the rest. What do the band say their best moment of 2012?

"I think it's always a really hard question when we get asked our top moment," Harry Styles told MTV News. "Madison Square Garden was definitely one of the top things we've ever done and will ever do. I think it just topped off an amazing year for us, and it's just been amazing."

Zayn Malik concurred, "We've had a big year." That may be the understatement of the year!
