The chef, Kai Chase, said on "The Early Show" Friday that, even though the King of Pop "looked good," he mentioned that the rehearsals were taking a toll.
"This tour was very important for him," Chase told co-anchor Maggie Rodriguez. " ... He (took) me to the side and told me, 'You know, I really need you to make sure that I'm eating organic and healthy. I know you know what you're doing, and I know you know what to do. That's why you're here. They're killing me. They're killing me. I'm working so much. I'm rehearsing a lot.'
"But, you know, he -- it was just a lot. It was just a lot of rehearsing, and he needed those organic juices, fresh organic beet juice. He asked me, 'Do you have my beet juice? Do you have my beet juice? Do you have my organic green apple lemon ginger for energy?" '
Still, said Chase, "He was very excited about the 'This Is It Tour."
Chase said she'd "never seen any evidence of drug use" in Jackson's rented Los Angeles mansion.
She also said she was "very shocked" to learn Jackson hers was one of the aliases Jackson was using to get prescription drugs, and that Jackson never told her. "This is all news to me. It's unbelievable. It's very shocking," Chase said.
Chase also laid out the timeline of what happened in the mansion the day Jackson died, saying his physician, Dr. Conrad Murray, came downstairs an hour-and-a-half later than usual that day and, at one point, agiated, asked to speak to Jackson's son, Prince.
Murray has been described in court filings as the target of a police probe of possible manslaughter in Jackson's death.
