Halloween is the night of ultimate reinvention, but for many well-known figures, a spooky costume just won't do. By emulating their favorite fellow A-listers, these celebrities pushed their costumes to the next level on October 31. There are plenty of amazing celebrity Halloween costumes to take inspiration from, including Justin Bieber dressing up as Ryan Reynolds’ ‘Free Guy’ character and that one time when Kim Kardashian dressed as Selena Quintanilla-Pérez.
Other notable examples include Anderson Paak dressing like Stevie Wonder, Prince, and Bruno Mars album covers, Hailey Bieber paying homage to Britney Spears, and
Rihanna channeling rapper Gunna. What about the time when
Cardi B showed up as Medusa, Margot Robbie worked as Ginger Spice, and Bella Hadid dressed as a Roy Lichtenstein painting? Another striking appearance was that of a hugely pregnant Emily Ratajkowski, who resembled the classic Vanity Fair cover photo of
Demi Moore.
