A source close to the situation explained:
OK, that's not true, we had a gajillion questions! But first and foremost was, "How??"
"Justin reached out to Selena after she canceled the tour. He wanted to make sure she was OK and healthy. He cares about her a lot."
That concern segwayed into friendly hangouts. But will it (and has it) become more? The source says:
"I don’t know if they’ll get back together. But he wanted to see her and spend time with her."
Well, they're definitely doing that! And from the looks of things, it's all quality time!
