Too much history to tell the whole story here. But suffice to say, there's been a lot of bad blood between Taylor and Katy over the years. So much so, that Taylor wrote a song called 'Bad Blood.' Good to see they're taking positive steps to get past whatever transgressions are in their collective past.
