Heidi Montag Pulls the Plug on Divorce

TMZ has learned ... Heidi Montag has officially called off her divorce from Spencer Pratt.



The two had been seen out in public together recently -- but yesterday, Montag made the reconciliation official, filing a motion for dismissal at L.A. County Superior Court.

As we previously reported, Montag filed for divorce back in July -- citing irreconcilable differences.

But now, after the two reunited in Costa Rica to deal with a sex tape scandal -- it seems Heidi is once again on board with the whole "'til death do us part" thing.
