Carrie Underwood, Shania Twain Help Save the Children

The world has been riveted by tragic images of starving children in East Africa, and now several of music's biggest stars, including two of country music's finest, are working to help combat the devastating crisis.

Carrie Underwood and Shania Twain have joined the campaign to raise money for Save the Children's East Africa cause. The ladies join fellow music superstars Paul McCartney, Coldplay, the Rolling Stones, Justin Bieber, Rihanna, Madonna, Lady Gaga and several more, who are all combining their efforts to raise crucial funds.

As part of the initiative, artists will each post a short film on their Facebook and Twitter pages of the urgent crisis, set to the music of Bob Marley's classic 1973 hit, 'High Tide or Low Tide,' and share how their fans can help. The goal is to reach one billion people, and raise millions of dollars to send food and financial aid to the more than ten million individuals who are starving in East Africa.

Marley's widow Rita is a strong advocate of the new endeavor. "Not one child should be denied food nor water," she notes (quote via 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."
