The Jackson family is feuding again … and this time it’s over the Michael Forever Tribute Concert that is scheduled to take place on October 8th in Wales, Great Britain.

According to our buds over at Radar Online, the main reason why the Jackson family is at war is because Katherine Jackson is allowing Michael’s three children to attend the event. And not only that, but Michael’s brothers Jermaine and Randy are also upset at the timing of the concert, which is scheduled to go down around the same time Dr. Conrad Murray’s involuntary manslaughter trial will be going on.

“Randy and Jermaine just don’t think it’s a good idea for Katherine, who is 81 years old, to fly all the way over to Britain for the concert, along with Michael’s children. Prince and Paris need to stay in school, and not be used for publicity. Jermaine is very concerned about his mother’s health because of the stress she is under with the upcoming trial of Dr. Murray. Katherine has vowed to be at the trial as much as possible, and her sons are concerned about the toll that all of this is taking on her”, a source close to the family told the entertainment site.

Another twist to the story is that the website selling tickets specifically confirm that MJ’s mother and children will be attending the event. “Michael’s mother Mrs. Katherine Jackson has agreed to attend the Concert with as many of Michael’s children as are available.”

Smokey Robinson, Christina Aguilera, Leona Lewis and Cee Lo Green are all scheduled to perform at the concert.
