This gives a whole new meaning to “Chillin’ It.”

Country biggest stars are taking part in the latest viral sensation called the “Ice Bucket Challenge.”

The likes of Cole Swindell, Luke Bryan, Darius Rucker and Dierks Bentley have all accepted dumped a bucket of ice water on their heads and then challenged someone else to do the same.

And it’s all in the name of a good cause.

The “Ice Bucket Challenge” is aimed to raise awareness of ALS or amyotrophic lateral sclerosis, better known as Lou Gehrig's disease. Major League Baseball and the ALS Association have partnered to “strike out” the disease at ballparks.

To date, the “Ice Bucket Challenge” has raised $2.3 million for the national association since July 29, according to USA Today.
