The X Factor judge was nominated for the charity dare by colleague Simon Cowell after he completed the same challenge yesterday.
Celebrities and members of the public have to dump a bucket of ice cold water over their head and make a donation to ALS Association. Other stars who've done it so far include David Beckham, Ben Affleck, Cristiano Ronaldo and billionaire Bill Gates.
Cheryl took on her icy challenge in what appears to be a very tropical location. Well, if you're going to do it, doing it in the sunshine is probably best!
That didn't stop the gorgeous singer screaming though when the water hit her!
Watch Chezza's ice challenge...
Cheryl has nominated her best pal Nicola Roberts, TV host Piers Morgan and One Direction singer Liam Payne to take on the challenge next. We'll await their videos...
On a non-related note, are those French swear words on Cheryl's T-shirt?
Fans on Instagram were quick to point out 'putain merde' is a French swear phrase. Perhaps something Cheryl learned from new husband Jean-Bernard Fernandez-Versini?!
