Actress Olivia Wilde took the ALS Ice Bucket Challenge to a whole new level by claiming to dump her own icy breast milk over her head instead of water.

The ice bucket challenge with breast milk may be tied to a recent photo shoot she did with Glamour Magazine where one of the photos shows her breast feeding her three-month-old son Otis.

In the ice bucket video, Wilde says she couldn't find water, so she claims she took all night to make the bucket full of breast milk.

Wilde later admitted on her Twitter page,

Oh wait some of you thought that was really breast milk? Oh dear. Uh thank you? But my boobs aren't that generous. Haha."

While it's comforting to know she didn't waste breast milk she could have fed to her baby, we didn't really know the level of generosity of her boobs.
