"Madonna likes nothing more than rolling up her sleeves and shoving her hands down a blocked well," a source told Britain's Daily Mirror newspaper. "She likes to do her bit.
"When she adopted David she promised his dad she'd stay in touch and visit often."
The Material Girl hitmaker is also planning to raise funds for the country — among the poorest in Africa — with a concert in the near future.
"She has big plans to raise money, including a possible charity concert next year," the source said.
Madonna has recently been seen out with a new man, 24-year-old dancer Brahim Zaibat, and it is believed her planned trip to Africa was one of the reasons she broke up with former boyfriend, Brazilian model Jesus Luz.
However, Brahim will not be accompanying her on her trip as friends confirm the pair are involved in a "no strings-fling".
"Madonna and Brahim are not serious — they are having a no-strings fling," said the pal. "He certainly won't be making the trip."
