The FOX News host has been in a contentious court battle with his ex-wife, Maureen McPhilmy, over custody of their 13- and 17-year-old children, and now it appears to have been decided once and for all by NY courts.
As Gawker first reported, the kids are said to have "clearly stated" their preference to live with their mother, leading the court to unanimously determine that they should live full-time with McPhilmy.
Last week in a unanimous court ruling, longtime Fox News personality Bill O'Reilly lost custody of his two teenage children.

Mr. O'Reilly had previously insisted he had sole legal custody for those matters. But a person familiar with the case tells Gawker that the motion most likely arose from O'Reilly's belief that his ex-wife was interfering with the custody arrangement for their 17-year-old daughter.
O'Reilly issued a statement at the time calling the allegations '100 percent false'.
"I am going to respect the court-mandated confidentiality put in place to protect my children and will not comment any further", he added.
The court process was a lengthy one - lasting since 2011 following O'Reilly's divorce from McPhilmy.
Since their legal separation, O'Reilly has been seen to try and undermine his wife on a number of occasions, according to reports.
Being able to influence his children's religious observation would likely be a priority for O'Reilly, who is well-connected within the Catholic Church.
In 2004, O'Reilly settled a sexual harassment lawsuit leveled against him by a former producer for the 'Falafelgate' scandal, who claimed he repeatedly subjected her to "lewd, lascivious, vile, and threatening" behavior.
