Sometimes what we hear turns out to be just gossip though... even when it's about the biggest band in the world: One Direction!
Here's some of the secrets we've heard:
- Niall spent over four hours in the make-up chair to transform into an old man for the Best Song Ever.
- Louis once dressed up in a fat suit and went around the city hugging people.
- Liam would be a sloth if he could be any animal, because they get to be lazy, don't need to look impressed and they see the world upside-down!
- The boys eat Gummi Bears before every show for good luck.
- It only took them a month for One Direction to record their album Take Me Home.
- Zayn bites his lip when he's nervous.
- Sometimes Harry doesn't do his hair at all - however it is when he wakes up is how he leaves it.
Erm, not this hair... this hair!
