Alexandra Burke says the damage in Haiti is of "Biblical proportions".
The 'Broken Heels' singer is in the earthquake ravaged country's capital Port Au-Prince where she is helping with relief efforts to assist the survivors of the two huge earthquakes which devastated the country last month.
Alexandra visited a Save The Children camp and met with Kiki Joachin, hailed the 'miracle boy' after he was found alive in rubble after being trapped underground for days. He later found out he had lost three of his six brothers and sisters in the quake.
Alexandra said: "Everything people said is true, the damage here is of Biblical proportions. The desperation of so many people has broken my heart.
"Despite going through hell, Kiki is still here smiling. He's beautiful. I didn't know what to say to these people who lost so much.
"His family lost three other kids in the quake. I was really nervous. I broke down in tears when I read about them."
Kiki's picture is on the cover of the Helping Haiti charity single, a cover of R.E.M's 'Everybody Hurts' - which Alexandra sings on.
She added to The Sun newspaper: "Kiki is the bravest person I've ever met. I'm honoured to meet him and to sing on a record that has his picture on the front."
Speaking from the Save The Children Camp, the star urged everybody to buy a copy of the single to raise money for aid relief.
She said: "So many children homeless, so many lives ruined. It's these kids who bear the brunt. But to see them singing and dancing at this centre makes me so proud.
"You see the poverty and destruction in the papers or on the news, but nothing prepares you for this.
"It's like being punched in the stomach. I just hope millions buy the 'Everybody Hurts' single. This is a whole country on its knees."
