Omarosa is going all 'Fire and Fury' on Donald Trump, because the publisher of her upcoming book says it's "explosive" and "jaw-dropping."
The former Trump adviser signed with Gallery Books ... this after appearing on "Celebrity Big Brother" and ominously warning housemates, "It's not gonna be okay."
Omarosa was fired from her White House job after a blowup at a White House holiday party.
She hasn't spilled any beans, but during at least part of her time at 1600 Pennsylvania Ave, she had Trump's ear and frequently had chitchats with him in the Oval.
