Taylor Swift is now a billionaire. That's according to the latest Bloomberg Billionaire Index, which now lists Swift's net worth at $1.1-billion. Her record-breaking and highly successful “Eras Tour” boosted the U.S. economy over the summer with more than 50 shows, and more dates scheduled next year. The pop icon has also been releasing re-recordings of her first six studio albums, including a new version of "1989," which came out today. Her new “Eras Tour” movie has been a box office smash, becoming the highest-grossing concert film ever on an opening weekend. Tay is one of the few performers to achieve billionaire status on music and performance alone.
