Ex-Kardashian Nanny Shopping Tell-All Book

 The help is turning on the Kardashian clan … TMZ has learned a former family nanny is shopping a tell-all book about her time with the K-squad before they were famous … and it’s clear she HATED some of the kids. Sources tell us … the woman behind the book, Pam Behan, served as a nanny, personal assistant and cook for Bruce and Kris Jenner for years … and spent all sorts of time with the Kardashian girls AND the Jenner boys, Brody and Brandon.

We’re told … in the book, Pam makes it clear — she couldn’t stand Bruce’s sons … calling the two kids, “extremely spoiled and disrespectful.” In the book, we’re told Pam also claims she almost lost her job after slapping Brandon one day.  As for the Kardashians — we’re told Pam describes her relationship with Kris as a “love/hate” thing … but she seems fond of Bruce, claiming he helped her avoid prosecution when she was busted for DUI a while back.

We’re told Pam also promises to reveal some “intimate details” about Kourtney and Kim —  surprising, because we’re told the girls were very fond of her. Sources tell us the book has been pitched to several major literary agents — but it’s unclear if a deal has been struck.
