Just like his dad, Brooklyn is doused by a huge bucket of freezing cold water, making him jump up and hilariously run around screaming.
Brooklyn then nominated a few friends, including Gordon Ramsay’s son Jack. We hope this leads to the celebrity chef having to take the challenge…
Victoria, 40, shared the video of her son, and hinted that her own ice bucket challenge is coming.

She tweeted: "Brooklyn's turn for the #ALS #icebucketchallenge! Getting prepared for my turn! X vb"
The fashion designer's celebrity bestie Eva Longoria nominated her, and we can't wait to see the normally immaculately groomed Posh covered in water.

It could possibly turn out to be the best thing ever, and we shouldn’t have to wait for long as the rules of the challenge mean you have to do it within 24 hours!
