The ghost writer of Michael Jackson's Moon Walk book claims to have tapes in which he called his brothers "Lazy Moaners." ET's Kevin Frazier talks to Jermaine Jackson to get his reaction.

"I've never heard that at all because our energy that we created as the Jackson Five, it never went away," Jermaine tells Kevin. "We put so much into our daily work, our rehearsals. We knew in order to achieve something great, we had to put in the blood, sweat and tears. It started with my father, 'Let's rehearse, lets get going. You got to do it over and over again.' If we grew up like that how could we become lazy? We are use to hard work."

Jermaine also tells Kevin that he saw part of the footage of the upcoming 'This Is It' film, hitting theaters this week and he feels that the title fits: "It's just that moment that comes in everyone's life."

As Jermaine and his brothers get ready to launch their A&E reality series, chronicling the Jackson brothers' lives and showing them grappling with Michael's death, he thinks back to the Jackson Five's heyday when he and Michael shared center stage as the group's lead singers.

"My relationship with my brother was great," he says. "We were the two lead singers of the Jackson Five. We were two of a kind. Our relationship was very close. I fought to the very end just to make sure that he was ok. I always had his back regardless of whatever I had his back"
