Ariana Grande has canceled what would be her first concert since her split from Pete Davidson.

The pop star pulled out of a scheduled show New Year's Eve weekend at the Cosmopolitan hotel in Las Vegas, TMZ learned. Sources close to the singer say she's been sick all week with no signs of getting better soon. According to the outlet, she's currently suffering from bronchitis.

Grande's show was scheduled to take place at The Chelsea, a 3,200 seat venue inside the casino. Tickets to the show were reselling for over $1,000 each.

The show will be rescheduled for a later date. It's not yet clear when she plans to do the performance.
