The 52-year-old singer ' who has adopted children David, five, and Mercy, four, from the African nation, as well as biological children Lourdes, 14 and Rocco, 10 ' plans to make a visit to help with charity work and allow David to see his biological father before the end of this year.

A source said: 'Madonna likes nothing more than rolling up her sleeves and shoving her hands down a blocked well. 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.

The source added to the Daily Mirror newspaper: 'She has big plans to raise money, including a possible charity concert next year.'

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'.

The source said: 'Madonna and Brahim are not serious ' they are having a no-strings fling. He certainly won't be making the trip.'
