During Halloween in 2023, Kourtney Kardashian chose to emulate her sister Kim Kardashian by replicating her iconic 2013 Met Gala outfit. Despite being pregnant with her fourth child, Kourtney confidently recreated Kim's floral Givenchy ensemble, reminiscent of the time when Kim herself was expecting her first child, North.
Rita Ora completely transformed herself into Post Malone for Halloween in 2018. She wore a wig, false facial hair, and fake replicas of the famous face tattoos that are distinctive to the artist known for his song "Better Now."
Her portrayal of Post Malone was so convincing that a news outlet mistook her for the Grammy-nominated artist. Ora shared this amusing incident during an appearance on The Tonight Show Starring Jimmy Fallon in May 2019. She recalled seeing the tweet and thinking that someone was going to lose their job for the mix-up. Ora also mentioned that she received numerous tweets from people thinking she was actually performing at the Grammys, to which she humorously responded that it wasn't her.
