Good Bad Billionaire - Selena Gomez: Actress, singer, beauty mogul

Selena Gomez is one of the youngest newly minted billionaires, thanks to her Rare Beauty brand. But you likely know her from her Disney kid days on The Wizards of Waverly Place, award-winning turn in Only Murders in the Building, or as the chart-topping singer of Lose You to Love Me.

BBC business editor Simon Jack and journalist Zing Tsjeng take us back to Selena’s early days on Barney & Friends, through her meteoric rise to fame - and the heavy cost that came with it. From intense tabloid scrutiny and public breakups to mental health struggles and a chronic autoimmune disease. Selena then made it all very public with her documentary My Mind & Me. She’s transformed her personal struggles into a mission to destigmatize mental health issues, pledging 1% of proceeds from her Rare Beauty company to the cause.

And as you’ll find out, there’s much more to Selena Gomez’s rise, fall, and billion-dollar reinvention than the tabloids ever let on.

Good Bad Billionaire is the podcast exploring the lives of the super-rich and famous, tracking their wealth, philanthropy, business ethics and success. There are leaders who made their money in Silicon Valley, on Wall Street and in high street fashion. From iconic celebrities and CEOs to titans of technology, the podcast unravels tales of fortune, power, economics, ambition and moral responsibility, before inviting you to make up your own mind: are they good, bad or just another billionaire?
