Challenged by his former Manchester United teammate Darren Fletcher, the current Ballon D'Or holder Cristiano Ronaldo was one of the celebrities who accepted the Ice Bucket Challenge.

Wearing only his CR7 underwear, Ronaldo was sitting on a chair when his Spanish club Real Madrid teammates, including Fabio Coentrao, poured two buckets of ice cold water on him, Metro reported.

Prior to this, the 29-year-old soccer player nominated "American Idol" judge Jennifer Lopez, Beyoncé Knowles and Lil Wayne.

Among the sports celebrities who did the challenge like Ronaldo are his Manchester United teammates Gary Neville and Paul Scholes, ice hockey player Paul Bissonnette, NBA superstar Lebron James and golfer Chris Kennedy, who is credited to the popularity of the challenge on social media.

While Jay Z's wife and the "Love Me" singer have yet to respond to Ronaldo's nomination, Lopez participated in the ALS Ice Bucket Challenge and took to Facebook to share a video of her version of the viral activity.

Before her twins poured ice cold water over hear head, Lopez announced her three nominees to take the challenge, who are former Scientology member turned reality television star Leah Remini and rappers Iggy Azalea and Pitbull.

Other singers who also took part in the Ice Bucket Challenge include "American Idol" alum Carrie Underwood, Justin Bieber, Taylor Swift, Al Yankovic, and former N'SYNC members Justin Timberlake, Lance Bass and Joey Fatone.

Ronaldo did the Ice Bucket Challenge for the benefit of the James McCarthy Foundation, Daily Mail reported.

Meanwhile, President Barack Obama refused to participate in the challenge after being nominated by several celebrities including Bieber but has agreed to donate the aforementioned $100 to the ALS Association instead.

In the United States, the Ice Bucket Challenge is intended to raise funds for the neurodegenerative disease Amyotrophic lateral sclerosis (ALS), which progressively shuts down the body's use of muscles.

It reportedly affects 30,000 people in the United States, where it is known as the Lou Gehrig's disease, and around 450,000 people across the globe, according to Guardian Liberty Voice.
