Louis Tomlinson, Liam Payne, Harry Styles ALS Ice Bucket Challenge Instagram VIDEOS: Zayn Malik's The Last One Direction Member To Get Soaked - When Will It Happen?

Niall Horan took the ALS Ice Bucket Challenge earlier this week and then challenged Louis Tomlinson to do the same. It took him more than 24 hours, but he did it! Plus his One Direction bandmates Liam Payne and Harry Styles also got soaked! In a collection of Instagram videos, three of the four members of the boy band took part in the ice bucket challenge and nominated some others as well. Now we're just waiting for Zayn Malik's video!

Louis' video, he gets two buckets poured on him by some pals before screaming and jumping into a lake. We hope that this video suffices for all of the fans that started the trending hashtag on Twitter "Louis Do The Ice Bucket Challenge." We think it was worth the wait!

He actually posted two videos, so check them both out right here:

Meanwhile, Harry also took part in the challenge, posting the following message in the caption to his video:

"Wake up call. I nominate Irving Azoff, Kanye West and Susan Sarandon.... And Ben Winston. Donate too."

Watch Harry get soaked from a distance in his Instagram video right here:

Last but hopefully not least (looking at you Zayn!), Liam got a room full of girls to pour the ice water onto his head. He also nominated his girlfriend Sophia Smith to take part in the challenge as well. Watch his Instagram video right here:

Only time will tell until we'll see Zayn follow in his pals' footsteps and get super cold and wet for a good cause!
