Madonna turned the spotlight on Malawi when she adopted son David from there in 2006. Three years later, she fought a ruling from the African nation that barred her from bringing home Mercy. The Big M prevailed, and in 2009, she winged Mercy home to London in a private jet. "I live a very privileged life," said Madonna, who is also mom to Lourdes and Rocco. "I know there are so many children in the world who don't have parents. I felt like I owed it. I had that responsibility."
