Justin recently revealed that wants to help raise funds for those who have been affected by the devastating natural disaster sweeping across the state and Niall, who has a home in Los Angeles, wants to help.
He told Mirror Online: ''We both live in LA and that's not too far from my house really where all those fires are kicking off, it's absolutely horrific. Three to four hundred homes destroyed and people's lives in tatters, so I thought about it when Justin reached out and sent that video.
''Of course if something is going on like that [a charity single] it's a no brainier, if he needs a hand with something I'd love to give him a hand.''
Justin shared a video on his Instagram account, in which he pledged his support.
He said: ''I'm going to have a conversation with some people and we are going to get moving on a solution. Obviously I'm not a fireman but I can use my resources to figure out ways to get some sort of restoration in certain communities.
''Fundraisers or whatever we can do. I'm going to get on that and in the meantime all the families and everyone who are struggling, just know that everything is going to be OK.''
Other stars also offered their support too, with Niall posting under the photo, ''Good man. Give me a shout if ya need a hand (sic)''
And Patrick Schwarzenegger wrote: ''Let's do it buddy.''
It comes after Justin donated $25,000 to the American Red Cross in aid of their relief efforts after Hurricane Harvey.
Speaking in a video clip posted at the time: ''Just looking at these photos from Hurricane Harvey. I just want to say that I am so sorry to all the families that have lost their homes, people that have lost their lives. I'm going to accept the Kevin Hart challenge and donate $25,000 towards the Red Cross, and I love you guys in Houston. You guys are awesome, you guys are strong. I am so sorry this is happening.''
