*A Bob Marley song has joined forces with the social media of such Twitter-happy celebrities as Lady Gaga, Rihanna and Eminem to help solve the crisis in East Africa.

On Tuesday, the “I’m Gonna Be Your Friend” campaign was launched to raise money and awareness, reports the AP. About 10 million are suffering through a famine in Somalia due to a blistering drought.

A short film about the crisis was set to the Marley & the Wailers song “High Tide or Low Tide.” Stars like Beyonce, Jennifer Lopez, Justin Bieber and about 150 others have pledged to promote it and the cause on Facebook and Twitter.

The video will be for sale on iTunes, through Bob Marley’s Facebook page and the website of the campaign. Funds raised will be donated to Save the Children.
