You've heard of amicable divorces, right?

How about amicable divorcees battling it out for a best director Academy Award?

With a rousing win to cheers at the Directors Guild Awards on Saturday night, "The Hurt Locker" director Kathryn Bigelow may have edged out former husband James Cameron, who helmed the blue-tinged mass appeal money machine "Avatar," in the race for a directing Oscar.

It was a historic win; the first ever feature-film DGA victory by a woman.

We won't know until tomorrow morning if Bigelow and her "king of the world!" ex will even draw Academy Award nominations.  If I were a betting man, though, I'd bet the house and the squirrel and bird feeder (which we love) that the former marriage partners will vie for the director golden statuette March 7 in Hollywood (and on ABC).

According to an article posted on the Hollywood Reporter Web site, the DGA's feature-film award is one of the best gauges of likely Oscar success in the director category:

"The Academy Award for directing has gone to someone other than the DGA winner only six times since the guild launched its awards in 1948, most recently in 2002 when Roman Polanski copped the Oscar for 'The Pianist' and the DGA crowned Rob Marshall for 'Chicago,'" the article states.

The win is sure to add a little early morning drama to the Academy Award nomination announcements tomorrow.  They'll be rattled off around 7:30 a.m. Central Time.
