Tonight on ET, we have another Jackson exclusive: Jermaine Jackson, on the record about family infighting -- and the real reason he pulled out of a scheduled photo shoot with his brothers.

ET's own Kevin Frazier was with Jermaine at a Hollywood photo shoot for his upcoming A&E reality series (and possible album cover), just days after brothers Marlon, Tito and Jackie posed without him in New York. Jermaine's image will be Photoshopped in with them for the final picture.

Back in New York, Marlon told Kevin, "[Jermaine's] in California. He's got pink eye. But when I see him he's gonna have a black eye!" A short time later, Jermaine was seen with Marie Osmond at the premiere of "Dancing with the Stars."

In response to Marlon's joke, Jermaine says, "They know that it had to be a real reason for me not to be there, because we've had thousands of picture sessions together all our lives. … I was exhausted. My eyes were so bad. It wasn't pink eye, but it was something that was just so irritated my eyes [were] red and just really awful."

"I had been traveling so much and I had been getting two hours of sleep and my eyes were just not right," he continues. "I was taking antibiotics. So I said I might as well just try to do mine out west."

The family's upcoming series, planned before brother Michael Jackson's death, and Jermaine's efforts to produce a now-cancelled tribute to Michael has the media questioning the Jackson family's motives, and that angers Jermaine, especially when they say that they're cashing in on Michael's death.

"That is absurd," says Jermaine. "That is the most ridiculous thing ever. It is not about cashing in on what has happened. It is responsibility on all of our parts as brothers and sisters to keep his legacy alive.

"I would love to see something done in my brother's honor every year, because he was that well respected around the globe," he continues. "So for the media to say this is absurd. It is stupid. It is crazy. Because we want the world to know we have created this as the Jackson 5 -- that was the foundation of Michael's success, of Janet's success, of everybody's. How are we cashing in on something that we created?"

Jermaine now plans to hold that first tribute next year in London. But there is more speculation that his brothers and sisters are not involved and there is infighting within the Jackson family.

"We are all brothers and sisters, but at the same time I don't have to tell them every time I am going to move," responds Jermaine. "I wish that they would move too and do creative things too. I would support them just as well. Who said I have to get an okay to do something for my brother? It is crazy."

Tomorrow on ET, tune in for new revelations from our Jermaine Jackson exclusive!
