ArianaGrande needs to look after herself! The songstress has actually cancelled what was to be her very first performance following her separation with Pete Davidson in October, due to disease.

Grandeis apparently experiencing bronchitis, avoiding her from singing, obvi. But fans are hypothesizing there might be another cause for cancellation …

Ariana’s had what she’s called “the worst year”– with the unintentional overdose of her ex-boyfriend Mac Miller and her separation with future husband Pete Davidson right after. Perhaps she requires a little bit more time to recover prior to she leaps in front of a Las Vegas crowd to belt out her hit single “Thank U, Next?”

Arianawas set to do a gig at The Chelsea in The Cosmopolitan hotel in Las Vegas on Saturday.
