Blake Shelton and Miranda Lambert are officially single ... we've learned the judge just signed the divorce docs.

TMZ broke the story Blake and Miranda are ending their 4-year marriage and Blake filed for divorce. We now know Blake filed his papers 2 weeks ago.  

It's ultimately up to the judge to make sure everything's kosher and the divorce will go through, and that just happened. There's a shorter waiting period in Oklahoma than other states.

As we reported, the divorce was easy since Blake and Miranda had a prenup.

Blake posted a pic just 2 days ago showing his wedding ring on the appropriate finger. We're told as of today the ring is history.
