Please tell us you went to the store and bought that milk, Olivia?!

New mom, Olivia Wilde accepted the ALS Ice Bucket Challenge... with a twist!

In the video she says, "I hope it's ok, I couldn't find any water so I'm going to use breast milk." She teased, "It took me all night to make this."

Then she lifts up a bucket of ice milk and pours it over her head!

Earlier in the month, Wilde was photographed breastfeeding her 4-month-old son Otis, for the September issue of Glamour magazine.
