"I've had ENOUGH!" After two years in the White House fishbowl, fed up first lady Michelle Obama sobbed those emotional words to her husband during a tense confrontation.

In a blockbuster ENQUIRER exclusive, well-placed Washington, D.C., insiders have revealed behind-the-scenes details of President Barack Obama's heated face-to- face with his 46-year-old wife - a spat that erupted over headline-making comments attributed to her in a revealing new book.

According to the book, Michelle told France's first lady Carla Bruni Sarkozy, 41, that she absolutely detests her role as America's first lady, blasting it as "hell," and admitting: "I can't stand it!"

During the Obama's quarrel, "Michelle collapsed in tears and even threatened to divorce Barack if he seeks a second term as president," a source in the nation's capital told The ENQUIRER.

"At one point, Michelle was heard yelling, 'I hate you for dragging me through all this…I've had enough!'"

Another D.C. insider confirmed details of the fight, telling The ENQUIRER that the screaming match occurred after the first family returned to Washington following their vacation in Martha's Vineyard with daughters Malia and Sasha.

The next day Barack was NOT wearing his wedding ring and despite official denials, there's "trouble ahead", insiders told The Enquirer.
