Madonna has added a new addition to her family as Mercy Chifundo, the 3-year-old toddler adopted by the pop star, was secretly flown from Malawi to London early Saturday, according to People.com. Mercy joins big sis Lourdes and brothers Rocco and David Banda, whom Madonna adopted from Malawi in 2007. Mercy’s adoption was granted by Malawi high court June 12 after an earlier decision forbidding the adoption was overturned.—ZH
