Mariah Carey performs at The Colosseum at Caesars Palace on April 27, 2015 in Las Vegas, Nevada.

Just a little more than a week into her Las Vegas residency, Mariah Carey cancelled a show due to bronchitis.

"Hey guys," she wrote on Instagram. "I've been fighting bronchitis for the past few days.. almost better but on mandatory vocal rest per doctor's orders. I'm so sorry to cancel tonight's show but I promise to make it up to you!!!. Love you always, MC" 

Hopefully Carey will feel much better on Sunday, when she's slated to perform at the Billboard Music Awards.
