Oprah Winfrey was scheduled to tape an interview with Madonna this week about the pop singer's planned adoption of a 13-month-old boy from the African country of Malawi. The interview is scheduled to air on Winfrey's talk show, a spokeswoman for Harpo Productions Inc. said Monday. It will be Madonna's first TV interview about the adoption. Madonna traveled to Malawi on Oct. 4 with her husband, Guy Ritchie. They spent eight days visiting orphanages she is funding through her charity. The child, David Banda, was taken to London last week after Malawi's High Court granted Madonna and Ritchie an interim adoption order. Madonna, 48, has said she acted according to the law, but the toddler's father, Yohane Banda, said Sunday he didn't realize he was signing away custody of his motherless son "for good."Madonna has two children daughter Lourdes, 9, and son Rocco, 6."Now, for the first time, Madonna speaks out with her side of the story on the adoption controversy."The 48-year-old mother of two will tell Oprah about her decision to adopt the 13-month-old boy after visiting his orphanage and reveal whether she will keep him in touch with African roots. A spokesman for Madonna yesterday insisted David will be "free to live wherever he wants" when he turns 18. Madonna has been granted 18 months of foster care for David while she applies to legally adopt him but human right campaigners plan to launch a legal battle to prove that she side stepped Malawi's strict adoption laws. David's father put him in the care of the orphanage after his mother died, and he now claims he believed Madonna was only going to raise and educate his son before returning him to Malawi.
