I think at the very most, a text is exchanged.

Outside the music, they don't interact much at all. They don't go to dinner or have backyard BBQs. I doubt that any of the band members have even been to Jon's house in the Hamptons.

The friendship they have for eachother is on a different level. They've shared success together which includes all the highs and lows.

I do believe that they care for each other but they are business friends for the most part.

And Jon and Richie are NOT best friends! I don't think that they could stand each other. I think it's all a front for the camera.
