Dressed in just a black bikini, a shawl, sandals and sunglasses, Katy Perry took the ALS Ice Bucket Challenge on Tuesday to help fight amyotrophic lateral sclerosis, commonly called Lou Gehrig's disease.

The "Black Horse" singer posted a video documenting the event to Instagram, in which two topless men pour freezing cold buckets of water over her head. To her credit, unlike many of the other stars who have taken the public challenge, Perry handled herself like a champ, barely flinching before she nominated Madonna to take the challenge as well.
