London, April 6 (Inditop.com) Pop diva Madonna is in Malawi for a charity tour with her four children, including David Banda and Mercy who are from the African nation.

The singer, who has undertaken a number of aid projects in Malawi, is accompanied by her biological children, Lourdes and Rocco, as well as her adopted children.

She plans to introduce her adopted children to their birth parents and lay the first brick of her $15 million Raising Malawi Academy for Girls, a school due to be opened in 2011.

“She sees it as vital they understand their roots. Mercy’s meeting with her family will be particularly emotional as it’s the first time she’s see them since last summer,” femalefirst.co.uk quoted a source as saying.

Madonna is scheduled to visit a poverty alleviation project in a village in the country’s Mchinji district, where she adopted David.
