DSK’s ex-wife may sue Tristane Banon’s mother (VIDEO)

A combination of two images shows (at L) a picture taken in 2011 of former IMF chief Dominique Strauss-Kahn and a picture taken in 2004 of French writer Tristane Banon.

Dominique Strauss-Kahn’s ex-wife, Brigitte Guillemette, may file a defamation lawsuit against the mother of one of Strauss-Kahn's accusers.

Anne Mansouret, the mother of journalist Tristane Banon, who alleges that Strauss-Kahn (DSK) tried to rape her, earlier this week said she herself had "brutal" but consensual sex with DSK, the ex-chief of the International Monetary Fund, in 2000.

Guillemette, who is also Banon’s godmother, believes neither Mansouret nor her daughter, she told Le Nouvel Observateur, according to NY Mag.

"None of what that woman says is true," she said of Mansouret, adding that, "I am not one of her close friends, my daughter Camille was never a friend of Tristane Banon’s," as has been claimed.

New York magazine writes that according to Guillemette:

Tristane did not even meet her daughter Camille until after the infamous interview where she says DSK attacked her. She called up Camille seemingly out of the blue, mentioned she'd interviewed her father, and would love to get coffee and chat about it, which the girls then did. It wasn't until a second meet-up in a Latin Quarter cafe, supposedly, that Tristane told Camille about the sexual assault.

It's the latest installment in an incestuous tale that became somewhat more sordid when Mansouret, 65, this week told Paris investigators that Strauss-Kahn (DSK) "took me with the vulgarity of a soldier" the former IMF chief in his Paris office in 2000, three years earlier than the alleged attempted rape of her daughter Tristane by DSK.

Banon, 31, has accused DSK of trying to rape her in 2003 in a studio flat in the French capital, accusing him of acting like a "rutting chimpanzee" as he tried to rip off her clothes.

Previously, DSK is reported to have said "I slept with the mother" and then was "overwhelmed" by the daughter.

Police say Mansouret's encounter with DSK — at the Organization for Economic Coordination and Development (OECD), where Strauss-Kahn, now 64, was working as a special adviser, is part of the reason she waited eight years to report the alleged attack.

Mansouret, a senior official in the same Socialist Party, has told French news magazine L'Express that she kept quiet about her own ordeal until 2003, when Banon first claimed she was attacked by DSK.

She had advised Banon against going to the police, but according to the New York Post, citing L'Express: "also confided in a close friend, Brigitte Guillemette, who was none other than Strauss-Kahn's second ex-wife."

According to Mansouret, Guillemette confronted her ex-husband, during which he confessed, "I don't know what got into me. I slept with the mother ... I blew a fuse when I saw the daughter."

Guillemette denied the conversation ever took place, when contacted by L'Express.

Prosecutors say DSK, who had been a favorite to run for the French presidency, attempted to rape a hotel housekeeper during a visit to Manhattan on May 14.

He resigned his post as IMF Managing Director a few days after his arrest, when a judge put him under house arrest at a rented townhouse in New York.

The arrest was lifted July 1, but DSK cannot leave the country until his next court appearance in New York, at the start of August. His lawyers continue to insist that the sexual assault case against him needs to be dismissed, based on doubts over the credibility of his accuser, a hotel maid.

According to several reports, Manhattan prosecutors are even planning to drop all charges against him.

Meanwhile, DSK is reportedly venturing farther from New York City with his wife, Anne Sinclair. The couple attended two concerts at the Tanglewood Music Festival in in New England’s Berkshire Mountains, western Massachusetts, CBS reports.
