Despite being on holiday, supermodel Kate Moss couldn't escape the ALS Ice Bucket Challenge.
Make-up artist Charlotte Tilbury was taskted with posting the video of Kate, which shows her on the beach in a black Huit bikini, facing not one, but six buckets of ice-cold water.
"Kate has asked me to upload her ice bucket challenge for her," Catherine captioned the image. "Please support ALS and raise money for this very worthy cause."
Before facing the water, Kate nominated actress Liv Tyler, Jack Nicholson and radio presenter Nick Grimshaw to face the challenge.
