Niall has hinted that he'll team up with Justin on a charity single.
After Justin shared an Instagram video promising to help those affected by wildfires in California, Niall has told the Mirror Online that something like a charity single would be a no brainer and he'd love to give Justin a hand if he needs help with something.
Niall has also said that the blazes, which have forced tens of thousands of people to leave their homes, are "absolutely horrific".
