Spokeswoman Liz Rosenberg won't say where or when Madonna and her husband, Guy Ritchie, will reunite with the 1-year-old boy, David Banda. She does say that Madonna is doing her best "not to make it a public circus."
Rosenberg says the couple will have temporary custody of David for 18 months. The courts of Malawi will then evaluate them.
The 1-year-old boy left Malawi on Monday, flying on a chartered plane to South Africa and then on a regularly scheduled plane to London. He was accompanied by two Britons and two Americans, one of whom listed her occupation as nanny.
Meanwhile, human rights groups have asked Malawi's courts to review Madonna's request for adoption. They're concerned the country bent the rules because Madonna gave the country a lot of money.
The Malawian immigration official said Monday that though he saw only a U.S. visa in the child's passport. He understood from those traveling with David that they were headed to England, where Madonna has a home, via South Africa.
The U.S. Embassy would not comment, saying visa issues were private.
Human rights groups want Malawi's courts to review a ruling allowing Madonna to adopt the child from this impoverished, AIDS-stricken southern African country, saying they want to ensure child protection regulations were not swept aside to benefit a pop star who has been generous to the country.
The Malawi High Court granted preliminary custody to Madonna and her film director husband Guy Ritchie on Thursday, even though the law requires would-be parents to live in the country for a year while social welfare officers investigate their ability to care for a child.
Justin Dzonzi, a lawyer for a coalition of human rights and child advocacy organizations, said his group had filed documents Monday asking a judge to review the adoption.
