Camila Cabello has been killing it since she broke up with her former girl band, Fifth Harmony. Ever since she parted ways, citing irreconcilable differences and the girls not down for her solo efforts, the 21-year-old released her debut self-titled album that placed well on the charts and won her the Chart Achievement award at the recent Billboard Awards. 

It seems as though all her hard work and non-stop attitude have caught up with her as she was recently told by a doctor that she needs to rest due to dehydration. 

"So yesterday after my performance at the billboards, i was feeling really sick and ended up in the hospital to get checked out," she tweeted. "They ran a lot of tests and everything is fine, but the diagnosis was basically dehydration and I also have a low grade fever - the doctors have told me I really have to get rest otherwise I won't get better - so unfortunately I won't be able to perform my set during the Reputation tour in Seattle tomorrow."

Camila's latest track is the Pharrell assisted "Sangria Wine," listen here.
