One Direction are one of the biggest musical groups on the planet right now, so it's no surprise that fans sometimes get a little overwhelmed when they meet the guys in person!
Here are some of the craziest, strangest fan moments the guys say they've had:
Zayn: “We were in Ireland, there was a girl by the bus and we waved at her and she fainted"
Niall: "We left Radio City and there were hundreds of girls running after the bus through traffic."
In a separate interview, Liam revelaed this: "Somebody hid in a bin and tried to break in to a police car that we were in and got arrested as well."
But there is a line – Zayn said that nobody has showed up in his hotel room. He added “but they get in the hotel. They book a bunch of rooms on our floors."
You’ll be able to see more 1D on the E! special “15 Awesomest Boy Bands.” The Wanted are on there too! It aired on Tuesday, so make sure to look out for reruns.
