Billie Eilish is gearing up to head out on her Happier Than Ever tour next month, but fans in select North American cities will have to wait a little longer to see her.

On Tuesday (January 25), the pop star revealed that a few of her dates had been postponed due to "local guidelines" and the Grammys' rescheduled date. Her stops in Toronto and Montreal in mid-February are being rescheduled "due to local guidelines and an abundance of caution;" however, new dates have not been revealed. Her second Phoenix date on April 3 was also rescheduled to the following night (April 4) because of the Grammys.

After her North American trek is over, Eilish is set to headline Coachella, which will take place April 15-17 and April 22-24. See her updated list of tour dates below.
