Sugababes star Keisha Buchanan was so moved by street children she met during a recent trip to South Africa that she wants to adopt.

The 'Push The Button' singer burst into tears after meeting 12-year-old Nokwanda, a rape victim from Durban who has been abandoned by her family.

Buchanan recalled: "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."
