Late Michael Jackson had become so weak in his final days that he was spoon-fed, his make-up artist has revealed.

According to Karen Faye, 53, the King of Pop was "disorientated and sickly" in his last week, and insists that the pressure of his London shows "killed" him.

She was by the ‘Thriller’ star's side at rehearsals in Los Angeles in June for his comeback at the O2 Arena in Greenwich.

Karen told Jacko's fans on Facebook that choreographer Kenny Ortega was feeding the singer.

"He (Jacko) was 12-20 pound heavier in April than he was in June. Kenny was cutting his chicken and feeding it to him,” the Sun quoted Karen as saying.

“This was one of my concerns. If he cannot feed himself, how could he be expected to do these shows?" she added.
