Celebrities have been participating in the ALS Ice Bucket Challenge all month , and this week, members of the Beckham family got in on the fun. David was the first one up for the challenge — he uploaded a video of himself  shirtless  and giggling during his stunt on Tuesday and a few hours later, his 15-year-old son, Brooklyn, was put to the test. After rattling off his nominations, Brooklyn knelt down as David and a friend showered him in freezing-cold water. His reaction is pretty hilarious, as he runs around the backyard yelling "It's so cold!" while being laughed at by his younger siblings — at one point, we can even hear what we think is the tiny British accent of 3-year-old Harper shouting Brooklyn's name as he rolls in the grass.
When Victoria shared Brooklyn's Ice Bucket Challenge  video on Twitter, she added, "Getting prepared for my turn!" but it wasn't until Thursday that the designer shared her own challenge which was executed with the help of her boys. Most recently, Victoria and David's youngest boy Cruz got soaked; Victoria tweeted, "Cruz's turn!" with a cute video showing his brothers Brooklyn and Romeo dumping the water and ice mixture on him with full force.
