When Bruni and Sarkozy kept a head of state waiting while they had sex

New York, May 8 (ANI): A new book has revealed that French First Lady Carla Bruni bragged to US First Lady Michelle Obama about how she and her husband French President Nicholas Sarkozy kept a head of state waiting while they had sex.

"Bruni wanted to know if, like the Sarkozys, Michelle and the President had ever kept anyone waiting that way," the New York Daily News quoted Alter as writing.

"Michelle laughed nervously and said no," he stated.

"The Promise", a book by Newsweek senior editor Jonathan Alter, is due out from Simon and Schuster on May 18. (ANI)
