Welsh schoolboy Shaheen Jafargholi proved an instant hit at the Michael Jackson memorial, becoming one of few artists to win a standing ovation from the packed stadium.
The largely American crowd roared with approval as the 12-year-old belted out his rendition the Jackson Five hit Who's Lovin You?.
Choreographer Kenny Ortega praised the youngster and revealed that the King of Pop had personally requested his appearance in his London concerts after watching the child on Britain's Got Talent.
Ortega said: "Shaheen was invited by Michael to join him in his London shows so I just wanted to introduce him to everybody and to say thank you."
After delighting crowds with his performance, Shaheen, wearing a black suit with white T-shirt and yellow flower, said: "I love Michael Jackson.
"I just want to thank him for blessing me and everyone on this earth with his amazing music."
Shaheen has sung in the Jackson stage musical Thriller Live!.
