In a bombshell world exclusive, The ENQUIRER can reveal that a top-notch team of private detectives has compiled a secret file containing incriminating new charges that President Barack Obama has cheated on his wife!

Sources say the hush-hush divorce dossier was gathered for first lady Michelle Obama and gives her the ammunition she needs to pull the plug on their 21-year marriage when Obama leaves the White House in 2017.

And sources say it will be costly to the outgoing president, whose earnings are expected to reach $100 million through lucrative book deals and appearances. The explosive file further contains shocking details about drugs and booze, Hawaiian hookers and a Secret Service cover-up linked to the President, sources say.

The ENQUIRER has also obtained the names of 12 women linked to Obama.

“Michelle now has all the dirt on Obama’s women,” a top Washington, D.C., source told The ENQUIRER. “A private detective has compiled her secret divorce file, and it contains incriminating charges of cheating by the President.”

An Insider Added: “Barack won’t have a prayer if he tries to defend himself. The secret file details his every flirt, fling and grope, and how Michelle was humiliated by the many women Barack lusted after.

“The file, which has been hidden away for Michelle, consists of notebook entries and other information. Some comes from private investigators hired by members of her inner circle through contacts in Chicago and Washington.”

The revelation of the smoking gun comes on the heels of The ENQUIRER’s recent report that the president was caught in a cheating scandal with the first woman named on the list – high-powered politico Caroline Kennedy.

The irate first lady angrily accused Caroline, now U.S. Ambassador to Japan, of publicly humiliating her during the president’s recent diplomatic trip there, sources said.

Obama, 52, traveled without his wife, and during his visit, a top Japanese government official blasted Michelle and ripped the first couple’s marriage, triggering her fury, sources say.

Next on the list is Helle Thorning-Schmidt, the dishy prime minister of Denmark. Obama brazenly flirted with the 47-year- old blonde during the memorial service for the late South African icon Nelson Mandela in December.

Obama even posed with Thorning-Schmidt for a now-infamous “selfie” that quickly went viral as Michelle fumed nearby.

Just weeks later, Michelle learned that the Secret Service had concealed her husband’s unfaithfulness, covering up flings with two mystery ladies.

Sickened by Obama’s behavior at the Mandela event, several loyal supporters decided to pass secrets to Michelle while she was vacationing in Hawaii in late 2013, the insider said.

“She learned that Barack was caught with a woman on a solo overseas trip, an incident that, in the words of one mole, was ‘hushed up,’ ” said the source.

“Besides that, a Secret Service agent also saw the president ‘in a compromising position’ with another woman while Michelle was out of town.”

And now private eyes have confirmed those affairs and learned new details, including “pillow talk” with the two women in which Barack slammed Michelle.

Also on Michelle’s list is actress Gabrielle Union, who’s engaged to Miami Heat basketball star Dwyane Wade. The first lady flew into a fury when the team was honored at the White House for its 2013 world championship, and her husband couldn’t stop leering at Gabrielle.

Obama’s fascination with the 41-year-old beauty sparked an uproar when one Internet site described the president eyeing her as if “she were the last hot dog at a cookout!”

As The ENQUIRER also reported, Obama was smitten with “Scandal” hottie Kerry Washington, whom he appointed to his arts and humanities committee. The president also invited her to speak at the 2012 Democratic national Convention.

When MIchelle found out Kerry was invited to her hubby’s second inauguration, she ripped into Obama, telling him: “Stay away from that woman!” A jealous Michelle even got a new hairstyle that closely resembled the 36-year-old actress’ look and went on to ban the now-married star from the White House.

Next on Michelle’s list is 22-year-old Miss Israel, Yityish “Titi” Aynaw. As we reported in April 2013, the first lady blew up after Barack gushed over the beauty queen at a state dinner held in his honor in Israel.

At the time, Obama enraged his wife by calling the exotic 5-foot-11 Miss Universe contestant “very beautiful,” adding that Michelle would love to be her height.

The president also caused a ruckus after lusting over California’s 49-year-old Attorney General Kamala Harris. At a Democratic fundraiser in April 2013, he unabashedly praised Harris as “by far the best looking attorney general in the country,” adding: “It’s true, come on.”

In late 2012, we revealed that Michelle exploded after Obama was photographed ogling Thailand’s stunning then-prime minister, Yingluck Shinawatra, 46, during a state dinner in Bangkok.

Another name contained in Michelle’s dossier is Alexandra Daddario, a 27-year- old actress who stripped naked on HBO’s hit series “True Detective”! As we reported, the commander in chief went gaga over the blue-eyed brunette, hinting that a “True Detective” marathon was in the works during his Valentine’s Day weekend retreat in Rancho Mirage, Calif.

Michelle didn’t make the trip.

Michelle’s file also includes information on superstar singer Beyonce after French journalist Pascal Rostain claimed in the reputable newspaper “Le Figaro” of an outrageous affair between Obama and the 32-year-old spitfire.

In his Feb. 10 story, Rostain pointed out that such an affair was not unheard of in American politics, writing: “We should not forget Marilyn (Monroe) or Monica Lewinsky,” referring to their flings with former presidents John F. Kennedy and Bill Clinton.

Although a Beyonce rep immediately squashed the rumors as “absolutely ridiculous,” it marked another humiliation for the first lady.

An entry in Michelle’s file concerns Barack’s continuing interest with his high school prom date, Megan Hughes. The blonde beauty claims the couple made love on their prom night when she was 15 and Obama was 17.  An insider claims Obama has stayed in touch with Megan, 49, behind his wife’s back – even sending her an autographed copy of his 2006 memoir, “The Audacity of Hope.”

“He wrote a personal note on the inside cover and signed it ‘Barack,’ ” said a friend of Megan.

The file also details how Barack still plays golf with high school buddy Bobby Titcomb, who was arrested in an undercover prostitution bust in Honolulu.

“Michelle was not only outraged, she wondered why the president would hang out with someone who solicits prostitutes,” said the insider.

“She believes something shady is going on.” accordIng to D.C. sources, Michelle’s file also includes information on the president’s past drug use.

Obama has openly admitted that he used marijuana and cocaine in high school. And in his 1995 book, “Dreams from My Father: A Story of Race and Inheritance,” he mentioned an incident when he apparently considered shooting up heroin.

“Michelle’s file raises questions in view of his lenient attitude toward marijuana,” said the insider.

The top D.C. source added: “The president loves alcohol, as well. These days he drinks beer, wine, martinis, sparkling wine and margaritas. In fact, I don’t think he’s met a drink he doesn’t like!”

The mortified first lady has already met with divorce lawyers, and as The ENQUIRER has reported, she’s told pals she’s found a new home for her post-White House days in Washington, D.C., and plans to have daughters Malia, 15, and Sasha, 12, live with her.

Meanwhile, Obama reportedly plans to settle in his native Hawaii, where he’ll live with longtime pal Titcomb. “The divorce file is all the protection Michelle needs to leave the marriage,” added the source. “This will be Barack’s punishment for the many humiliations she’s suffered.”
