A former nanny of the Kardashian's is trying to sell a tell-all about the family, and promises to reveal secrets about the ever-expanding brood.

Pam Behan served as a nanny, cook and personal assistant for Bruce and Kris Jenner when their children were little, and according to TMZ, she is trying to shop her book which dishes the dirt about her time working with one of America's most famous families.

In the book, Pam reportedly labels Bruce's children Brody and Brandon as "extremely spoiled and disrespectful," and she also claims that she was almost sacked when she slapped Brandon.

According to Pam, she has a "love/hate" relationship with matriarch Kris, but is fond of Bruce after he helped her out following a DUI arrest.

She also has "intimate details" about Kourtney and Kim to reveal, despite the girls apparently getting on well with her.

The website reports that Pam is yet to sign a book deal despite pitching it to several literary agents.
