Being a pop star is hard work for sure! Rehearsals, dancing, singing, awards shows, tours, the whole thing can be so exhausting! And unfortunately sometimes those pop divas and dudes get worn down. Fans of Camila Cabello were sad to learn that she will not be performing in Seattle tonight. Camila is one of the scheduled openers for Taylor Swift on her Reputation tour, but due to "dehydration" and a low-grade fever, she will not be performing in Seattle tonight. Camila took to Twitter to apologize to her Seattle fans.
