Katherine Jackson's lawyer is officially squaring off with the two men Michael Jackson selected to handle his estate, claiming the co-executors are intentionally trying to keep Jackson's mom in the dark.
Londell McMillan just issued a statement making it clear -- he wants Katherine to become a co-executor. McMillan claims the co-executors -- John Branca and John McClain -- are not letting Katherine see the agreement Jackson signed with AEG. ... which McMillan says could be a huge source of income for the estate.
McMillan claims the co-executors are imposing unreasonable demands on Katherine -- requiring her to make special promises of confidentiality for the benefit of AEG.
The co-executors have maintained all along they were the ones Michael selected to manage the estate and they are doing their job.
One thing is clear -- it's getting ugly.
UPDATE 9:43 AM ET Reps for the co-executors just issued a statement, saying the only thing the co-executors asked of Mrs. Jackson is a confidentiality agreement with respect to the AEG agreement but her lawyers refused. They also say it's apparent Katherine's lawyers want to "rewrite Michael's will to make Mrs. Jackson 'Guardian of the Estate' and have her appointed as an executor" ... the co-executors say it's just not what Michael wanted and he said so in his will.
