Ice Bucket Challenge Roundup: Harry Styles, Liam Payne + More [VIDEOS]

The ALS Ice Bucket Challenge continues to be one of the most successful viral fundraising campaigns, which as of Friday, Aug. 22, has directly led to $51 million dollars being raised for ALS Research, according to the ALS Association.

In case you have been living under a rock over the past week, the campaign has had everyone from your next door neighbor, to the likes of Justin Bieber and Taylor Swift, challenging friends to either videotape themselves pouring a bucket of ice water over themselves, or donate money towards ALS (aka Lou Gehrig's disease) research. Many celebrities have done both, which some say will change the way money will be raised in the future.

In today's roundup, we take a look at Harry Styles and Liam Payne as they finally accept the challenge, much to the delight of One Direction fans everywhere. Actor Mark Wahlberg participated in the challenge with the help of his wife and kids. 'Star Trek: Into Darkness' star Benedict Cumberbatch takes his video to epic levels. We also have videos from Taylor Hanson of Hanson, The Script, Charli XCX, Brian Littrell of the Backstreet Boys, and actor Josh Dallas.

Check out the videos below! Remember, if you want to contribute to the cause on your own, please visit the ALS Association website for more information.
