“I got the call three days ago to be a part of this. Bono and Jay-Z called me up, they wanted me to be a part of it, and, of course, anything that can help Haiti, I want to be a part of,” Rihanna told MTV News on Friday night. “This song is really important. Lyrically, Jay-Z gets really, really deep in his verses, more than I’ve ever heard him get. He gets really real. I know a couple of people he’s singing about. We have mutual friends that suffered loss, they lost their family, they lost friends, and it really hits home. So this is really a song for Haiti, letting them know we are not going to leave you stranded; we are going to do every last thing to help you. You are not alone.”

Her voice trembled slightly as she spoke — just more proof of how deeply this tragedy has affected her. Like she said earlier in the week on “Oprah,” where she performed a haunting version of Bob Marley’s “Redemption Song,” she’s from the Caribbean nation of Barbados. It’s not a stretch to say the footage coming out of Haiti hit her close to home.

“When I first heard about it, I was at home, and I kind of didn’t believe it. I was in such shock. An earthquake in Haiti was shocking to begin with. And [one of] that extent; a 7.0, that’s huge, that’s unheard of,” she said. “And being from the Caribbean, I was in shock for a long time. And when I started looking at the pictures, at the footage, seeing that little boy get beaten up for food, seeing people trapped under the rubble, kids not knowing where their parents are, bodies just getting dropped outside of the hospitals, that just made it really real.

“It made me want to do something about it, I wanted to help, because we all have to help,” she continued. “And now my role is to encourage more people to help, to join with me to help.” – MTV
