In the last few years, a very simple business plan has emerged among Hollywood's most elite: be rich, start a beauty business, become a millionaire, repeat. Rihanna has done it, Selena Gomez has done it, Kylie Jenner has done it, and now Hailey Bieber has done it.
Once stars cross the billion-dollar mark, they immediately begin dressing from a whole new playbook. Gomez, for example, has made the little black dress her standard, having worn dozens of styles (if not more) since joining the billionaire's club. And one 10-figure beauty merger later, Bieber is now following in her footsteps.
