Everyone knows that Oprah is Barack Obama's biggest supporter so it's a story such as this that makes us question whether it's true or not. 

According to a new book, The Amateur: Barack Obama in the White House, written by former New York TImes Magazine editor Ed Klein, Michelle and Oprah have been at war for a while. 

After Michelle rejected Oprah's request to have her on the show to talk about obesity, Oprah went around saying, "Michelle hates fat people and doesn't want me waddling around the White House." Michelle is also apparently jealous that her husband calls Oprah often for advice on how to gain popularity.
