Buchanan Considers Adoption.SUGABABES star KEISHA BUCHANAN was so moved after meeting street children during a recent visit to South Africa she is considering following in MADONNA's footsteps and adopting a child from the continent.The 22-year-old cried after meeting 12-year-old NOKWANDA, who was raped three years ago before being abandoned by her relatives, on the outskirts of Durban.Buchanan says, "She said, 'I wish you could visit all the time, why do you have to go?' It broke my heart, what can you say to that? I know I will see her lovely face in my dreams forever."Meeting children like her makes me understand why Madonna felt compelled to adopt. It is definitely something I would consider one day."
