Josh Kushner's parents refused to meet his wife Karlie Kloss for six years and 'spoke horribly' about her behind her back, an expose of the family claims.
Charles and Seryl Kushner, whose other son is Jared, the son-in-law of Donald Trump, banned Kloss from family gatherings because they hated her so much.
The Kushners hated how Kloss was not Jewish and the family, who were billionaires thanks to their real estate empire, thought that a Victoria's Secret model was beneath them.
Family friends mocked Kloss as 'the lingerie model' and they feared that Josh had 'doomed' the entire bloodline.
Jared, whose wife Ivanka Trump is a Jewish convert, also piled in and dismissed Kloss as a 'shiksa', a disparaging term for a non-Jew.
He also said that the 'family is going to take care of that', according to Kushner, Inc.: Greed. Ambition. Corruption. The Extraordinary Story of Jared Kushner and Ivanka Trump by Vicky Ward.
The claims in the book by the journalist author shed new light on Josh and Kloss' relationship which began in 2012 and had a six year courtship.

Last summer Josh's parents appear to have finally relented and they agreed to meet Kloss, even letting her stay at their beach house for a long weekend a few months before their wedding last fall (pictured)
The couple got engaged in June last year and soon after Kloss converted to Judaism in a move which now looks designed to please her husband's parents.
Kloss, the new host of 'Project Runway', revealed in October that she and Josh had got married in a quiet ceremony in upstate New York - but only after the event.
Josh's parents were reportedly there as was Jared and their two sisters but it appears to be a very low key affair.
According to Kushner, Inc. Josh extracted revenge on his parents by not asking them to play any part in the nuptials, denying him the society event which he would have preferred and Charles was 'noticeably restrained' when talking about it to a family friend.
A Kushner family member explained why to Ward; saying Seryl thought that Josh's marriage to Kloss was her 'biggest failure'.
According to Kushner Inc. the family disapproved of Kloss right from the start when she and Josh began dating in 2012.
