Carrie Underwood and Shania Twain have joined musicians like Madonna, Lady Gaga and the Rolling Stones to help feed starving children in East Africa. In joining the Save the Children's East Africa cause, both singers have promised to record a video urging their fans to help.

Underwood has the organization's video posted at her page on Facebook. In the three minute long clip, one sees clearly the effects of of life-threatening drought that's plagued the area. At the end, the video urges viewers to visit to help. Bob Marley's 'High Tide or Low Tide' is the theme song for the cause, and his widow Rita Marley is a strong supporter of the cause.

"Not one child should be denied food nor water," she tells US Weekly magazine. "Not one child should suffer. Along with Save the Children, we must stand up together as friends to put a stop to this, to feed our children and to save their lives."

The goal is to reach one billion people and raise money to provide supplies, food and financial assistance to help the millions of people starving in East Africa. Paul McCartney, Coldplay, U2 and Justin Bieber are other artists who've pledged to help.
