Gwen Stefani looks all too eager to dump a bucket of freezing cold water on her friends and family for the ALS Ice Bucket Challenge!

The 44-year-old No Doubt frontwoman nominated her husband Gavin Rossdale, as well as her pals Jessica Alba and Nicole Richie, all of whom completed the task together while hanging out at a backyard party.

Gwen and Gavin‘s adorable son Zuma, almost 6, also got drenched while sitting on his dad’s lap, and he nominated his older brother Kingston, 8!

Gwen was originally nominated by fellow Voice judge Blake Shelton.
