Break out the bar of soap! Jessica Alba has been caught on camera dropping the F-bomb…

Don’t worry though, it’s all for a good cause!

The Mexican-American actress appears in a new PSA created by the anti-poverty advocacy group ONE.

Titled “The F Word: Famine is the Real Obscenity,” the minute-long clip aims to bring attention to the devastating famine occurring in Somalia. Other celebrities appearing in the PSA include George Clooney, Bono, Rob Lowe, Joe Jonas and Colin Farrell.

The Horn of Africa, the peninsula in East Africa that’s home to Ethiopia and Somalia is currently experiencing the worst drought in more than 60 years and it’s threatening the lives of more than 12 million people.

“More than 30,000 children have died in just three months. Mothers are forced to decide who to feed and who to let die. In 2011? That’s obscene,” says U2 lead singer Bono. “There are things that can be done, and if we really believe the life of a child in East Africa is worth the same as the lives of our own children, we have to act.”

The PSA is calling for the African governments provide the $650 million needed for assistance, and to fulfill their commitment to invest $22 billion in agriculture for African governments.
