She got there in the end! Victoria Beckham finally worked up the guts to take a freezing cold soaking in her own ALS Ice Bucket Challenge — and she was knocked to the ground under the force of the water!

Two days after husband David Beckham and son Brooklyn took the challenge, Victoria shared footage of her own dunking via Facebook on Thursday, Aug. 21.

Kneeling on the ground in her workout gear, the fashion designer announced she was ready to take up Eva Longoria's challenge to help raise money and awareness for ALS research.

With her voice growing gradually more hysterical as David and sons Brooklyn, Romeo and Cruz approached with huge buckets of water, the former Spice Girl challenged Tom Ford, Katie Holmes and her youngest son Cruz to take up the challenge themselves.

The boys in her family then had a blast, pouring huge amounts of freezing cold water on their mom's head, causing Victoria to fall onto her hands as she screamed out in shock.
