Outfoxed! Bill O'Reilly Muzzles Ex-Wife In Bitter $10 Million Lawsuit

TV bigmouth Bill O'Reilly is desperate to cover up the dirty details of his divorce to maintain his increasingly slippery grip on his status as the face of FOX News!

As his network was rocked by sexual harassment scandals, the 67-year-old O'Reilly Factor host persuaded a judge to seal details of the $10 million lawsuit he filed against ex-wife Maureen McPhilmy when she won custody of their kids earlier this year, insiders told RadarOnline.com.

And O'Reilly's blood is boiling!

"Bill doesn't like to lose," a source close to the newsman said. "He's gonna try to take Maureen to the woodshed."

Furious McPhilmy dumped him for New York police detective Jeffrey Gross, and the millionaire wants to bury anything from their six-year divorce and custody battle that makes him look bad, sources said.

O'Reilly has succeeded by whining to a civil court judge that he's so famous "matters concerning his personal life, marriage and children attract media attention," which causes his two kids "extreme emotional distress."

However, O'Reilly's 17-year-old daughter charges in court papers HE's the one creating distress. She claims she saw him dragging her mom down a staircase — by the neck!

O'Reilly is frantic to downplay the domestic abuse accusations and insists, "All allegations against me in these circumstances are 100 percent false."

Of course, he said the same when a FOX producer sued him for sexual harassment more than a decade ago — before settling out of court.
