Madonna defends adoption attempt

Madonna has defended her decision to adopt a second Malawian child, insisting she is "committed" to maintaining a connection to adopted son David Banda's homeland.

The pop superstar arrived in the African nation at the weekend with her 12-year-old daughter Lourdes, eight-year-old son Rocco, and three-year-old boy David, whose adoption was finalised in 2008 after two years of legal wrangling.
