The singer also said that he felt 'honoured' to be a part of the show, which includes spots from Christina Aguilera, Ne-Yo, Cee Lo Green, Alexandra Burke and Leona Lewis.
"Michael Jackson was probably the number one inspiration for all the songs I was writing because it was everywhere," he said.
"People in the furthest reaches will know MJ's songs. It's an honour to go back and perform in aid of him."
Discussing the other acts on the bill, he admitted: "I think Leona Lewis will do it justice. JLS - you know they're going to do a big, lavish performance. You can see them doing 'Thriller' - that's the one they'd kill."
He continued: "I've just got to make sure I pull it off. People don't want me to go up there and do a remix of the song. Just do the song... and kill it."
