London, July 1 : Rebuffing speculations about Michael Jackson's ill-health, his trainer and actor Lou Ferrigno has said that the King of Pop was in great shape.

"I''d never seen him look better," the Sun quoted him as saying.

The `Hulk' star and a bodybuilder Ferrigno was helping Jacko get in shape for his gruelling series of shows at the O2 in London next month.

He insists that he was stunned to see the `Thriller' hitmaker getting in shape for a massive comeback.

"When he moved he convinced me that he was going to make the biggest come back in history," he said.

"He was great. I trained him on and off for 15 years and when I saw him a few months ago, the way he moved - I''d never seen him look better," he added.

The two-time Mr. Universe insists that Jacko, who was said to have been taking "mountains of medication", "never" said anything about being in pain.

He added: "As a matter of fact sometimes he would be dancing, showing me the moves, between the sets, our exercising, and he convinced me, I said, ''This guy can pull it off''. When I saw him he was not frail."

The actor said that he was left "extremely devastated" by Jackson''s sudden death on June 25 (ANI)
