Kris and Bruce Pic

Well, it's over. After years of Kris and Bruce Jenner divorce rumors, the troubled couple has officially called it quits.

TMZ reports that Kris Jenner filed for divorce from her husband of 23 years today. Bruce has yet to respond. Remarkably, the proceedings are said to be taking place without lawyers, which suggests that it's an amicable split.

While it may not have been any one thing that led Kris to finally, legally bring her marriage to an end, it's long been rumored that Bruce Jenner is seeking a sex change, which prompted Kris to seek a separation in 2013.

The sex change rumors have never been confirmed by either party, and friends of Bruce's have denied that he has any interest in becoming a woman, but Jenner's changing appearance in recent months has led to increased speculation.

Most recently, sources indicated that Kris Jenner had taken to mocking Bruce for his increasingly feminine behavior. 

But regardless of what prompted, it the Jenners divorce will likely proceed rather quickly, legal experts say. The fact that Kris filed without legal counsel may even indicate that they've already reached an agreement.

The reality TV power couple laughed off divorce rumors as recently as last year, but insiders close to the Jenners claim they've been living separate lives for quite some time.
