Larry King‘s wife has secretly drawn up divorce papers, The ENQUIRER has learned exclusively.

Shawn King, the willowy blonde wife of the 75-year-old CNN talk-show host and mother of their two young sons, has told close friends that she’s met with a lawyer and may file for divorce at any time.

"Larry’s wife Shawn told me directly that all it will take to make her divorce filing official is just one phone call," a close friend, who passed a polygraph test, told The ENQUIRER.

"She says she has the papers drawn up, and one false move from Larry and that will be it. She says she’s already got everything in her name and all that’s left is the filing."

The ENQUIRER has exclusively documented a series of problems in the couple’s 11-year marriage – beginning with a shocking blowup reported in 2007.

That’s when the couple engaged in a "slapfest" outside the famed Beverly Hills eatery Nate’n Al after arguing over where to sit.

Then last summer, we revealed that Shawn, 49, was forced to enter rehab at the Betty Ford Center for a pill dependency.

In an exclusive interview, Larry said Shawn had been taking up to 20 powerful Vicodin painkillers a day to relieve migraine headaches.

But only four months later, Larry – who’s been married seven times to six different women – was said to be heartbroken…
