Michael Jackson learning to moonwalk again

The 50-year-old star is trying his best to be fit and agile enough to perform his famous dance moves for his 'This Is It' 50-concert shows at famous 02 arena this July.

Jackson's moonwalk is as iconic as the singer himself. He appears to glide backwards while walking forwards in it. But concerns are being raised whether the aging singer, who has been dodged with poor health rumours for sometime, will be able to pull off the physically taxing steps.

The Thriller hitmaker is reportedly spending hours studying old footage of his famous moves and is working with acclaimed choreographer Kenny Ortega and a team of fitness trainers to ensure he is fit to perform the moves, the Daily Mail reported.

"Michael has started working with a choreographer and trainers to get him in shape because he wants to perform the moves that made him famous. He is spending hours watching his past performances and videos because he wants to put on a show that is as good as those he's done before," a tour source told the newspaper.
