This wasn't Swift's only good deed in Phoenix, either. The singer took time out to visit 8-year-old Isabella McCune, who was left with burns covering 65 percent of her body after an accident in March. McCune was burned so badly, her bandage changes could take several hours, and she listened toSwift's music to stay calm. 。

McCune's burns will keep her from attending Swift's tour opener in Phoenix on Tuesday, so the pop star brought a little ray of sunshine to her young fan in a hospital visit.。

Yes, these are the kinds of things pop stars do from time to time to give back to fans and, yes, generate a little good PR buzz ahead of big events.。

But Swift is someone who does this sort of thing more than most, so it's good to see she's still up to her same, old charitable self, even if the "old Taylor" is, technically, well, dead. 。
