Joan Kennedy, 1st wife of longtime US Senator Ted Kennedy, has cleared that she has nothing to do with her son Patrick Kennedy's explosive tell-all book describing his father as an uncontrollable alcoholic. As per Joan, she did not have any knowledge that Patrick was even writing it and has not received its advance copy.

The tell-all book, ‘A Common Struggle: A Personal Journey Through the Past and Future of Mental Illness and Addiction’ unveils that Ted was suffering from disabling alcoholism. Joan’s statement is completely opposite of Patrick, who during an interview has claimed that he has consulted his mother. In fact, Patrick has also said that his mother was the only family member to support the project.

But now, in a statement to PEOPLE, Joan has distanced herself from the project by saying that she has not assisted Patrick in the project in anyway. She has also said that she has not read the book.

But Patrick's rep told PEOPLE that they would standby with their last statements. As per them, Joan was aware and has been very supportive of Patrick’s efforts as an activist of mental health and addiction.

Patrick’s brother Edward M. Kennedy Jr. affirmed that Patrick has depicted ‘inaccurate and unfair portrayal of our family’. He also said that he is quite upset by the book.

"I had no knowledge that Patrick was writing a book and did not assist him in the project in any way," Joan said in a statement relayed to PEOPLE by her close friend Margo Nash, a Cape Cod lawyer. "I was not given a copy of the book and have still not seen it or read it."

"That goes against what the process was," Valliere told the Globe Monday of Joan's statement. "She was aware and participated and has been very supportive of his efforts as an activist for mental health and addiction."
