Michelle Obama thinks being America’s First Lady is ‘hell’, Carla Bruni reveals today in a wildly indiscreet book.

Miss Bruni divulges that Mrs Obama replied when asked about her position as the U.S. president’s wife: ‘Don’t ask! It’s hell. I can’t stand it!’

Details of the private conversation, which took place at the White House during an official visit by Nicolas Sarkozy last March, emerged in Carla And The Ambitious, a book written in collaboration with Miss Bruni.
