Pop star Madonna and her husband Guy Ritchie will soon be questioned by a Malawian welfare inspector who will be checking to see whether they are a suitable family to adopt a one-year-old Malawian boy, The Sun reported on Monday.

Citing unnamed sources, the paper said that the director of Malawi's Ministry of Child Welfare Penston Kilembe would carry out the inspection at the couple's central London home in about two weeks.

The pair will reportedly be queried about their use of alcohol, as well as infertility, divorce and infidelity over five days.

"This home study is a big deal -- and Madonna and Guy have been absolutely dreading it," the source said.

"Malawi is a conservative country that disapproves of drugs, alcohol, divorce and cheating. These assessments are very gruelling and many couples don't pass."

The singer is in the process of adopting little David Banda and was awarded interim custody in October. According to The Sun, the inspection is the last legal hurdle in adopting the baby.

Kilembe could reportedly observe Madonna and Ritchie for up to five hours a day for up to five days, to judge how loving they are towards each other, as well as their children, daughter Lourdes and son Rocco.
