Miley Cyrus' divorcing parents came together for a peace summit -- and there's a strong sign tensions are easing between them.
Billy Ray Cyrus and Tish Cyrus took their daughter Noah out for lunch Sunday in North Hollywood -- but the interesting part -- Tish is leaning her head on Billy Ray's shoulder and they are arm-in-arm!!
Don't forget ... 3 years ago Billy Ray filed divorce papers, but eventually ripped 'em up and reunited with Tish.
You know what they say about history.
