Michael Jackson fans are up in arms over a letter circulating on the Internet that appears to be signed by several Jackson siblings, including Janet and Jermaine, threatening legal action against the executors of his estate.
In the letter, obtained by ABC News, five Jackson siblings accuse executors John McClain and John Blanca of fraud and abuse of their mother, Katherine Jackson.
"THIS HAS TO STOP NOW; NO MORE!!" the letter reads. "Before we hit the stage, we were a family and still to this day we are a family. We're not going to let anyone abuse our mother, nor will we tolerate any further attempts to divide us."
Thursday, Jermaine Jackson hinted on Twitter that there is more to come: "Re our letter to Estate: while fans only have limited info right now, we ask for patience because much is yet to emerge in this jigsaw..."
The letter, signed additionally by Rebbie, Tito and Randy Jackson, suggested that Katherine Jackson recently suffered a "mini-stroke" as a result of the longtime dispute between the executors and members of the family.
Her attorney disputed that Jackson was in poor health.
"Katherine Jackson is absolutely capable of taking care of the children and does a terrific job," her attorney, Perry Sanders, said in a statement to ABC News. "I have no reason to think that has changed in any way, shape or form. She does a phenomenal job, is extremely lucid and not having any difficulties of any consequence. It's unfortunate that anyone would paint Mrs. Jackson as anything but completely lucid and doing a great job with the children."
Even Jackson's daughter, Paris, 14, has chimed into the dispute.
"i am going to clarify right now that what has been said about my grandmother is a rumor and nothing has happened, she is completely fine," Paris tweeted Wednesday.
"The truth is that Mother DID suffer a mini-stroke some months ago," Jermaine Jackson tweeted Thursday. "She is fine now, but the timeline doesn't alter the fact it happened"
The relationship between the Jackson family and the singer's executors has been strained for most of the three years since Jackson's sudden death from an overdose of the anesthetic Propofol. Many of the allegations contained in the letter have been made by family members before. But the letter threatens new legal action against Branca, an entertainment lawyer, and McClain, a music executive -- both of whom worked with Jackson at different points in his career.
In response to the letter, estate spokesman Jim Bates said in a statement to ABC News, "We are saddened that false and defamatory accusations grounded in stale Internet conspiracy theories are now being made by certain members of Michael's family whom he chose to leave out of his will. We are especially disheartened that they come at a time when remarkable progress has been made to secure the financial future of his children by turning around the estate's finances as well as during a time when so many of Michael's fans, old and new, are enjoying his artistry through exciting new projects."
Bates also dismissed any claims that the will, which was validated in probate court in the months after Jackson's death on June 25, 2009, was somehow a fake.
"Any doubts about the validity of Michael's will and his selection of executors were thoroughly and completely debunked two years ago when a challenge was rejected by the Los Angeles County Superior Court, the California Court of Appeals and, finally, the California Supreme Court," Bates said in his statement.
"Under the supervision of Los Angeles County Superior Court Judge Mitchell Beckloff, co-executors John Branca and John McClain have diligently carried out their fiduciary duties as well as their obligation to Michael to make sure that his estate benefits the only family members he named in his will -- his mother and his three children."
