Pop Singer Madonna has blasted critics who have slammed her second Malawian adoption bid, insisting it is “none of their business.”

The 50-year-old is currently in Malawi to make 4-year-old Mercy James legally hers. James’ 18-year-old mother had died five days after giving birth to her.

However, the singer’s adoption plans have been hit by opposition from officials – as well as the girl’s family.
