Fans were quick to praise the precious twins, with one writing: "They are so adorable! Madonna, I'm very happy for you and your family!" Another added: "I don't normally comment but have to for this one. SUPER GORGEOUS!!! Thanks for the love of humanity."

The star announced the exciting news that she had adopted the twins from Malawi after a sharing a photo of herself holding hands with the two girls. She wrote: "I can officially confirm I have completed the process of adopting twin sisters from Malawi and am overjoyed that they are now part of our family. I am deeply grateful to all those in Malawi who helped make this possible, and I ask the media please to respect our privacy during this transitional time. Thank you also to my friends, family and my very large team for all your support and love!"

Madonna was granted an adoption on Feb. 7, and will be under observation by the court for a year before the process is finalized. Speaking about the process, judge Fiona Mwale revealed that she asked the star "rather uncomfortable questions" to ensure that she wouldn't stick to a "well-rehearsed speech".

She said: "The petitioner is a professional performer and I guarded myself against the danger of her merely reciting a well-rehearsed speech by asking her some rather uncomfortable questions to which she gave very candid answers". She confirmed that Madonna wanted to adopt the girls "to offer a home, love, protection and guidance".
