“Real Housewives of Orange County” alum Meghan King has temporarily lost custody of her three children to her ex-husband, retired MLB player Jim Edmonds … TMZ has confirmed.

Sources tell us the change came after a school employee allegedly filed a report with Child Protective Services about King. Following an investigation, CPS granted her supervised visitation with her children.

We’re told the arrangement isn’t necessarily permanent and a court hearing in December will determine whether this custody setup sticks for good.

Us Weekly first broke the news.
