"Queen of Mean” Michelle Obama has forced out another White House staffer – the First Family’s personal chef!

Kitchen magician Sam Kass got fed up with Michelle’s snippy comments and told the Obamas to take his apron and shove it, insiders told The 
National ENQUIRER.

“He just couldn’t take it – the relentless nitpicking, over petty little details that drove him insane. She thinks she’s Marie Antoinette!” a White House insider told The ENQUIRER.

“It has nothing to do with Sam’s cooking, which is superb. But you could be Wolfgang Puck and Michelle wouldn’t be happy. She’ll find some reason to turn up her nose, no matter how good a job you’ve done!”

Michelle habitually sends food back after serving, often with snide remarks, our well-placed source said.

“These are some of the world’s best chefs,” the source huffed. “It gets to be too much to bear.”

Sam, 34, cooked dinner for the Obamas five nights a week and has served as their personal chef since 2005. He also headed Michelle’s “Let’s Move!” fitness campaign to end childhood obesity.

He joined a conga line of East Wing staffers who couldn’t stomach the First Lady’s perfectionism, including her first chief of staff, Jackie Norris, who lasted just four months.

Sam was also the third executive director of Let’s Move! First was Robin Schepper, a veteran D.C. communications pro, who stayed on the job for less than a year. Next up, noted pediatrician Dr. Judith Palfrey, fled after only five months. In fact, a 2011 story on a website reported Michelle was already on her third chief of staff, third social secretary and second communications director. 

 “The first lady’s office can be a confining, frustrating, even miserable place to work,” a former White House staffer wrote in March under a story headlined, “The Worst Wing.”

“She’s your ultimate straight-A student; she was used to being perfect.”

Obama and Sam are also golfing buddies, and the Chief Executive hustled back from a 15-day Martha’s Vineyard jaunt in August to attend Sam’s bachelor party.

Sam’s resignation has upset the First Family’s fragile balance, which is reeling from allegations of the president’s philandering, sources said.

“It’s terrible, because Sam’s like a big brother to Malia and Sasha, having been with the family so long, going back to their days in Chicago.”

“Both kids were crying their eyes out that he’s leaving. But Sam is handling it with class. He hasn’t told either of them the real reason he quit is their horrendous mother,” added the source.
