A “boozed-up” Hillary Clinton suffered a secret collapse during a recent vacation – and now worried advisers want her to do a secret stint in rehab before her White House run!

Sources close to the former First Lady and ex-Secretary of State revealed the hush-hush “Rehab Before White House” plan to The National ENQUIRER in advance of Hillary’s formal announcement to be a 2016 presidential candidate, touted for early next year.

A high-level insider told The ENQUIRER: “Hillary’s social drinking has gone out of control!

“In a hushed-up incident, Hillary was too tipsy one night and suffered a secret collapse. One insider said she was ‘boozed-up!’

“Fortunately, she was okay, but no matter how much alcohol she had, it was a clear signal that she needs professional help.”

“Bill, in particular, who wants to see Hillary become president more than anybody, agreed that she must seek help – and they’ve devised a possible ‘cover story’ that she’ll take a few weeks at a ‘spa retreat,’” added another insider.

“Hillary needed to be present for daughter Chelsea giving birth. But after a few weeks of playing doting grandma for the media, they’ll place her somewhere Hillary has no say. However, a small group of trusted long-term aides have been quietly looking into which rehab facility is best for Hillary, a source divulged.

“The favorite so far is the Betty Ford Center in the California desert – but another contingency considered would be private counseling in a remote location to keep it as quiet as possible.”

Hillary has always been a drinker of wine and cocktails, but her boozing increased on long flights during her term as Obama’s Secretary of State, despite health problems.

“Now, Hillary can’t unwind if she doesn’t have a few drinks and end up tipsy,” the first source said.

“It’s also affected her in other ways. A couple of times she has flubbed a joke line, and her performance flailing her arms about Benghazi in front of Congress will haunt her.

“Talking about the four who were killed in the Libyan terror attack, Hillary blurted out, ‘What difference, at this point, does it make?’

“When Bill saw the remarks live on TV, he was said to be upset.

“Her advisers fear if she doesn’t quit drinking cold turkey, she’ll start making mistakes on the campaign trail that could be disastrous. If she seriously misspeaks or says something that sounds ridiculous, it will haunt her as a candidate.”

Added the second source: “Her opponents and enemies will run the embarrassing sound bites endlessly. For a potential presidential contender, these days, every word must be thought out and carefully delivered.

“They can’t risk a boozy Hillary caught off guard. Her drinking days, they’re determined, are numbered.”
