American singer Taylor Swift is a billionaire, according to the latest ranking of world celebrity fortunes. With assets now estimated at $1.1 billion, the Pennsylvania native becomes the first artist, male or female, to have crossed the ten-figure threshold solely thanks to income from her music.

In less than a year, Taylor Swift has seen her fortune grow by $360 million, largely thanks to the economic benefits of her 152-date monster tour The Eras Tour. According to several estimates, “Eras” is on track to become the highest-grossing concert series in music history, well over a billion dollars.
