Selena Gomez has officially become one of America's youngest self-made billionaires, with a net worth of $1.3 billion, primarily attributed to her successful cosmetics brand, Rare Beauty, which contributes roughly $1.1 billion to her fortune. Unlike her friend Taylor Swift, whose wealth is largely derived from music, Gomez's billionaire status stems from diverse income sources including acting, brand endorsements, and her mental health startup Wondermind. Gomez's authenticity and openness about her personal struggles, particularly with mental health, have resonated with consumers, enhancing the appeal of her brand. Experts attribute her success to her multifaceted approach as a businesswoman and her ability to leverage her extensive social media following. Additionally, Gomez's other ventures include partnerships with major brands and her acting role in 'Only Murders in the Building', contributing to her impressive wealth. As she navigates her career, Gomez remains committed to mental health advocacy, with a portion of her beauty brand's sales directed towards related initiatives.
