Mary Kennedy went to her grave convinced that her husband, RFK Jr., had a fling with the wife of the man who broke up the marriage of his sister and Andrew Cuomo, The Post has learned.
A heartbroken Mary confided to a group of her closest friends that she believed Robert Kennedy Jr. had an affair with well-connected fund-raiser Ann Colley, two of her confidants told The Post.
One source who claimed to have been told about the purported hookup said that, if true, “an affair with the wife of his sister’s paramour is particularly tacky — even for a Kennedy!”
Mary told friends the alleged affair started after Colley’s polo-playing husband, Bruce, began his highly publicized 2003 fling with Kerry, sparking Kerry’s nasty split from now-Gov. Cuomo.
Bobby Kennedy Jr. had been asked to step in as a peacemaker when the Cuomo-and-Kennedy scandal erupted.
Instead, Mary told friends, Bobby wound up “consoling” Ann, a longtime board member of RFK Jr.’s Riverkeeper environmental group.
Both Cuomo and Ann Colley divorced their spouses in the wake of the scandal.
Ann Colley yesterday denied any romantic involvement with Robert F. Kennedy Jr.
“The accusation that I had a romantic relationship with Bobby Kennedy is false,” she told The Post.
“We are professional colleagues and dear friends,” she said.
Mom-of-four Mary was so upset by her suspicions that she tried to have her perceived rival banished from Riverkeeper, said three people familiar with the situation.
“Mary tried to get Ann thrown off the board,” said a friend in whom Mary Kennedy confided.
But Ann — who directs the charity efforts of hedge-fund tycoon Louis Bacon’s Moore Capital Management — was a valuable asset. Bacon has sunk more than $1 million into Riverkeeper’s coffers over the years.
“There were those Bacon millions to consider,” said one friend, of Mary’s failed effort to oust Ann.
Riverkeeper board chairman Dr. Howard Ruben told The Post that Ann’s position on the board has never been in jeopardy.
“Ann has been a massively influential part of the Riverkeeper board, and her tenure has never been in question,” Ruben said.
Mary Kennedy hanged herself in her Westchester home last week.
Friends said she was inconsolable after Bobby filed to divorce her in 2010, cutting her off financially and parading new girlfriends in public.
The purported Colley affair was one of several a devastated Mary claimed she endured for much of her marriage.
“It just broke her heart,” said one friend. “And he didn’t care. He threw it back in her face, again and again.”
Since Mary’s May 19 funeral, the Kennedys — including Kerry, who was a “best friend” and boarding-school roommate of Mary’s — have been very vocal about what they claim was her longtime battle with depression.
“They want to make it look like she was crazy, that everyone tried to help but that Mary was hopeless,” said one furious friend.
“I’m sure Bobby is worried that all these stories are going to start coming out of the woodwork,” said another Mary confidant.
Kerry Kennedy’s affair with dashing, polo-playing Bruce Colley became headline fodder on July 1, 2003, a day after she and Cuomo announced they were ending their 13-year marriage.
Andrew’s friends said he had been “betrayed” by his wife.
At the time, Bruce Colley, whose father got rich on a massive McDonald’s franchise, was a part-owner of nightclub Man Ray and a social-circuit fixture.
It was Kerry, sources said then, who pursued the affair — but it was Bobby’s charity ties that put Bruce Colley on her radar.
Ann Colley handled philanthropy for secretive hedge-fund manager Bacon, who gave generously to Bobby’s Riverkeeper efforts.
When Bacon hosted an event at his private island off the Hamptons, Cuomo and Kerry attended and mingled with Ann and Bruce Colley, sources said at the time.
The two couples became fast friends, sharing family vacations, including Aspen ski trips, family friends said.
Cuomo caught his wife with Bruce and Kerry fessed up but refused to end the relationship. Ann Colley was also aware of the affair, friends said.
Robert Kennedy felt sorry for Ann, who was “the innocent one” caught in the middle, a source said.
And — after Cuomo begged his wife to go to counseling and talk to priests — Bobby was asked to step in.
“The idea was for him to convince his sister to end it with Bruce, or at least cool it,” a source said.
