The singer became the latest star to get dropped in the comedienne's 'dunk pool' - and she came prepared.
Wearing a form-fitting red one-piece bathing suit, matching swimming cap, high heels and nose band, Crow took her seat in the tank as the show host fired balls at a lever.
It took DeGeneres seven attempts to hit the target and drop a shocked Crow into the water.
Microsoft Windows Mobile bosses are donating $10,000 (GBP5,400) to DeGeneres' Ellen For The Cure cancer drive for every celebrity dunked during October (08), America's Breast Cancer Awareness Month.
Crow, a breast cancer survivor, added to the loot by handing over her own cheque, from Yoplait, for an additional $10,000.
