In Paul Scott's book "Tony & Cherie: A Special Relationship," he describes a litany of situations in which Cherie Blair was angered or disgusted, the Daily Mail reports.
The book also claims the hostility is mutual, though. It claims when Princess Anne first met Cherie Blair in 1997, the princess was curt and dismissive, leading Cherie Blair to call her a "bitch" to a companion.
The book also claims Cherie Blair considered the late Princess Diana "an airhead."
Although Cherie Blair, who turns 51 this week, has reluctantly agreed to curtsey before Queen Elizabeth in public, she refuses to in private.
When she and her husband make their annual stay at Balmoral castle, she suffers an allergic reaction to the fur and feathers of the stuffed animals and hunting trophies that adorn the castle walls, and reportedly has severe allergies to the queen's corgis. The book said she describes the Balmoral experience as "too unbelievably horrible for words."
