Randy Jackson is angry his brother MICHAEL's children were on holiday prior to the first anniversary of their father's death (25Jun10) - because he wanted the youngsters to visit the late singer's burial place with him.
Randy and his siblings, Janet, Jermaine and Tito, paid their respects to the Thriller hitmaker on Friday (25Jun10) at the Forest Lawn Cemetery memorial in Glendale, California.
But Jackson's children - Prince Michael, 13, Paris, 12 and eight-year-old Blanket - were enjoying a sunshine break in Hawaii earlier in the week (begs21Jun10) and failed to make it to the grave site.
In a post on his Twitter.com page, Randy writes, "Sorry Big Bro, for not getting ur (sic) children there on the anniversary of ur (sic) last day. I tried."
The 48 year old has also criticised his mother, Katherine, for approving a marble tribute to Michael on the lawn of the former family home in Gary, Indiana.
He adds, "I am not in support of the Gary event/trip or whatever it is... I'm tired but I promise to continue this discussion."
