"The little sisters are both aged 4 years and 7 months as they were born on 24 August 2012. The father is still alive but the mother died a week later after delivering the little kids on 29 August 2012," the Judiciary Spokesperson adds to ET.
"Madonna came to the court on Tuesday with her lawyer Mr. Mvalo. The father of the children was also in court together with the uncle of the little girls. She looked very happy in court. She left with her two new daughters."
The "Ray of Light" singer has adopted from Malawi twice before. In 2008, she adopted son David Banda with then-husband, Guy Ritchie. A year later, she went back to the country and adopted daughter Mercy James. Both children are now 11 years old.
Prior to her adoptions, Madonna founded the charity Raising Malawi in 2006, which supports orphans and vulnerable children in the African country through health, education and community support.
In addition to her now four adopted children, the singer also has two biological children, 20-year-old Lourdes Leon and 16-year-old Rocco Ritchie.
