PASSION PROJECT

Madonna – dressed in Gucci – premieres her documentary, I Am Because We Are, Thursday at the Tribeca Film Festival in New York. The film follows the lives of orphaned Malawian children – including her adopted son David Banda – and was directed by Nathan Rissman, who was once Madonna's gardener and helped look after her kids. "He started making home movies of my children," she told PEOPLE. "And they were amazing."
