Madonna's New Daughter Mercy Flown to London Overnight
"A private jet flew in from South Africa and collected her at five minutes to six last evening," an airport source tells PEOPLE. "She connected to London from Johannesburg at 10:30 p.m."
Mercy, who will be joining big sister, Lourdes, brothers Rocco and David Banda, – also a 3-year-old from Malawi – was accompany by a nanny, a child nurse and another aide. Madonna has homes in England and in the United States.
Malawi's highest court granted the adoption June 12, overturning an April court ruling that the pop star had not spent enough time in Malawi to be given another child.
Madonna, who was seen leaving London by private jet Friday afternoon after earlier flying in from New York's JFK airport, was still expected in Malawi, but no one could confirm when she would arrive.
"There are still preparation for her coming," said a source at Raising Malawi, the charity the singer set up in the African nation. "We still have a two-week booking at Kumbali Lodge."
The Lodge is an exclusive ranch Madonna has been staying during all three of her visits to Malawi. Owner Guy Pickering confirmed his place has been booked for two weeks but could not divulge more.
"We don't discuss our clients; that's private information," he said.
