It’s only a week into her Las Vegas residency, but the inimitable diva Mariah Carey already had to cancel a show.

The singer was unable to make her Wednesday night concert due to a bout of bronchitis. She made the announcement on Instagram, writing, “Hey guys.. 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.”

We’re pretty curious how she plans to make it up to Wednesday night’s ticket-holders (will she get them all butterfly-adorned charmbracelets?), but hopefully Mimi gets well soon. Vegas needs her.
