This speculation has increased since the release of her latest album, Petal, which was released on Friday, and her appearance in promotional material for the launch.
In the music video, Grande plays a performer who is repeatedly told in auditions that she is “not good enough”, is “desperate” and that she “should get some work done” then that she has “too much work done.” The character eventually takes a chainsaw to the critics.
Grande’s representative stressed to People that the star was looking forward to finishing her tour “on a high note, both healthily and happily, and then taking a much-deserved break from public-facing work and appearances, which has led to endless, ongoing public scrutiny”.
They added: “She performs a very physical show, and there is a lot of athleticism involved. She performs healthily and successfully at a very high level night after night.”
The tour continues in Chicago on Monday, with three dates at the city’s United Center. It will then move to London’s O2 arena for 10 dates from 15 August, with the tour concluding there on 1 September.
