David Beckham shirtless? We've never seen that before!

The soccer stud stripped down to accept Ryan Seacrest's ALS Ice Bucket Challenge Tuesday. Before he got showered with a bucket of ice water, he asked Leonardo DiCaprio, Magic Johnson and Michael Jordan to either do the same or donate $100 to fund amyotrophic lateral sclerosis research projects.

Beckham joined numerous stars who have raised awareness for Lou Gehrig's disease.

LeAnn Rimes accepted CMT host Cody Alan's challenge Monday. Before she got wet, Rimes revealed that she'd already made a donation and vowed to make one on a fan's behalf if he or she completed the challenge and sent her a link to the video. Eddie Cibrian and his sons then doused the country crooner.

Neither of their videos compare to Hugh Jackman's enormous effort, though. After Russell Crowe challenged his Les Misérables co-star, Jackman recruited the cast and crew of Pan—including Garrett Hedlund, Levi Miller and Rooney Mara—to join him. As dozens of people got wet 'n wild, colored smoke filled the air. They challenged Tom Cruise and the cast and crew of Mission: Impossible V, all of William Morris Endeavor's staff, plus Oscar Isaac and the cast and crew of Star Wars: Episode VII to follow suit.

Guardians of the Galaxy director James Gunn put the movie's heroine, Zoe Saldana, to the test. "Obviously I can't do it myself," the pregnant actress said while rubbing her baby bump, "so I nominate my husband [Marco Perego] to take on the challenge and get rinsed with an ice bucket of ice water."

Saldana nominated Ron Burkle, James Cameron, Eileen Getty and Salma Hayek.

Other famous participants included Chris Brown, Kaley Cuoco-Sweeting and Hillary Swank.
