Selena Gomez joined Bloomberg's billionaire list.

Selena Gomez, an American music star, is now a billionaire, according to Bloomberg's Billionaire Index.

The actress, singer, and entrepreneur built an estimated $1.3 billion fortune through her Rare Beauty brand, music, and successful shows.

According to the publication, Gomez's share in Rare Beauty Brand Inc. accounts for more than 80% of her net worth.

Brand alliances, acting gigs, and mental-health businesses all added to her wealth.

Gomez first gained popularity as a kid star in the 2000s. She reportedly earned around $3 million for her role as Alex Russo on the Disney Channel's Wizards of Waverly Place from 2007 until 2012.

She then pursued a music career, initially with the pop-rock band Selena Gomez & the Scene and later as a solo artist.

With 424 million followers, Gomez is the third most popular person on Instagram, trailing only sports icons Cristiano Ronaldo and Lionel Messi.

Music tours accounted for less than 5% of Gomez's net worth, while album and record sales made for less than 2%. She has not toured since 2016.

The majority of Gomez's fortune—roughly $1.1 billion—comes from her ownership in Rare Beauty.
