Madonna will visit Malawi on Sunday to lay the foundation stone of a multi-million dollar girls' school she is building, her charity Raising Malawi told Reuters.

She is due to arrive on Sunday and attend a brick-laying ceremony in Lilongwe on Monday. The school is expected to cost about $15 million.

"She plans to meet the President Bingu wa Mutharika and together lay a foundation stone for her multi-million dollar girls school," a staffer at the charity, who declined to be named, said on Thursday.
