Looks like the Donnie Wahlberg divorce is nastier than we first thought.

We broke the story a few hours ago that Wahlberg's wife, Kim Fey, filed for divorce last Wednesday. Right after the story went up, Donnie's rep contacted us and said Donnie actually filed the divorce papers, not Kim.

So here's where it gets good. We did more digging and we're right ... she filed for divorce in L.A. County Superior Court. The clerk stamped the papers at 1:29 PT. And then we found that Donnie filed his own divorce papers in Ventura County Superior Court the same day, at 3:46 PT.

So is this race to the courthouse a sign that each wants to make the point they're leaving the other? We're thinkin' so.
