“I’VE had enough!” Furious first lady Michelle Obama hurled those fight­ing words at her husband after he publicly humiliated her by flirting with a leggy blonde foreign leader at South African icon Nelson Mandela’s memorial ser­vice, sources say.

In a bombshell world exclusive, The ENQUIRER has learned that in the wake of the mortifying incident, Presi­dent Barack Obama and his wife are now sleeping in separate White House bedrooms.

Sources say an enraged Michelle is also preparing to boot her hubby of 21 years out of their ritzy Chicago home – and seriously discussing divorce.

“The smart money says the marriage is doomed,” said a close source.

“Barack and Michelle have had a rocky go for years and mainly stayed together for their daughters and his political career.

“But now Michelle is mad AS hell. She feels violated in front of the whole world, and screamed at him, ‘I’ve had enough!’

“She’s met with divorce lawyers and told Barack that she wants a life apart from him.”

An Oval Office insider added: “Mi­chelle will stay in the White House for the rest of Barack’s term for ap­pearances’ sake, but she made it clear they’ll be leading separate lives.

“She’s moving into one of the va­cant bedrooms in the family’s private living quarters, and she’s preparing to move his clothes and personal things out of their million-dollar house in Chicago.”

Sources say Michelle, 49, hit the roof after her lusty hubby was pho­tographed brazenly flirting with Denmark’s dishy female prime min­ister, Helle Thorning-Schmidt, during the service for former South African president Mandela.

Obama, 52, laughed and whispered with the 46-year-old Danish beauty throughout the solemn ceremony, at one point cavalierly caressing her shoulder.

The two also playfully snapped a “selfie” photograph together while Michelle shot daggers at them.

The Danish press has dubbed Thorn­ing-Schmidt “Gucci Helle” for her love of designer clothes.

While she lives in Copenhagen, her husband resides in Davos, Switzerland, and the couple’s accountant reportedly said that her husband was “gay or may­be bisexual.”

Obama’s outrageous antics with her made him the butt of international ridicule, with American media outlets going on the attack.

“New York Post” columnist Andrea Peyser blasted: “(Mandela) was a man who Obama compared at the memorial to Abraham Lincoln, Mahatma Gandhi and Dr. Martin Luther King. And here was the president, publicly behaving as if he was plotting his next hook-up. It was unseemly.

“…Not to be outdone by the presi­dent’s bad behavior, the Danish hellcat hiked up her skirt to expose long Scandinavian legs covered by nothing more substantial than sheer black stockings.”

Famed body language ex­pert Dr. Lillian Glass, who evaluated the photographs at The ENQUIRER’s request, was appalled at the presi­dent’s behavior. “This was clearly extremely humil­iating for the first lady,” Dr. Glass told The ENQUIRER.

“The president effectively ignored her and acted like he and the Dan­ish prime minister were the only two people around. And he did this with the whole world watching.

“The photos show Michelle going through a series of emotions, rang­ing from shock to anger and extreme jealousy. I think there are many changes occurring in their relation­ship.”

The president’s staff was also quick to criticize his horn-dog conduct, sources say.

“Barack already had enough head­aches with his public approval rating plummeting after the disastrous roll­out of his ‘Obamacare’ health plan. Now he’s walked smack into the worst marital crisis of his life,” said the White House insider.

“Behind the scenes, his advisers chewed him out, saying the photo­graphic images of his frat-boy hijinks will haunt him forever.

“On top of that, women voters have bombarded the White House with letters, phone calls and emails ex­pressing sympathy for the first lady and anger at the president.

“Even Obama’s top female advisers and friends like Valerie Jarrett were disappointed with him.”

Sadly for Michelle, the spectacle in South Africa wasn’t the first time the charmer-in-chief has crossed the line with other women.

But the couple’s fight over his be­havior with the sexy Danish leader was the worst ever, “and they’ve had some doozies,” said the White House insider.

“Rather than unloading on him in South Africa, where their privacy was not guaranteed, or on Air Force One among other high-ranking dig­nitaries, including George and Laura Bush and Hillary Clinton, Michelle reserved her fury until they were back in their private quarters in the White House. Then she went ballistic behind closed doors.

“Barack has humiliated Mi­chelle before, but this incident was played out on the world stage. Practically everybody on the planet saw what he did and realized that the president has absolutely no respect for his wife.”

Meanwhile, The ENQUIRER has learned the first couple plans to live nearly 5,000 miles apart when their days at the White House come to an end. Obama reportedly plans to settle in his native Hawaii, where his presidential library and political center will be located. Sources say he’ll live with his longtime pal Bobby Titcomb, who was busted for soliciting a prostitute in 2011.

Michelle will remain in Wash­ington, D.C., until the couple’s youngest daughter Sasha, 12, finishes high school. Daughter Malia, 15, is a high school sophomore.

For now, Michelle is gearing up for a nasty divorce battle. But sources say she’ll most likely wait to slap Barack with divorce papers until after he leaves the Oval Office, when he’ll likely earn more than $30 million in book deals and bank $65 million in appearance fees.

“Now that Barack has embarrassed Michelle in front of the world, he’s going to pay a big, big price,” said the insider. “Michelle has said she wants a huge chunk of his net worth.

“This divorce is going to cost him a fortune.”
