Grande, who announced last month that she would step back from all future public appearances following intense speculation about her health and appearance, made her final tour stop in London. During the show, she asked the audience for help while performing 'One Last Time,' kneeling down to be near fans throughout the song.
The singer's voice also faltered during 'Nowhere, Nobody' as she sang the line 'Hard to believe in a perfect ending,' but she quickly regained composure and delivered a professional performance.
On stage, Grande showed no signs of fragility despite a foot injury that forced her to swap her trademark stilettos for knee-high platform boots. She still moved energetically, often compensating for the lost heel height by performing on tip-toe.
As part of her step back from public life, Grande has withdrawn from a scheduled production of Stephen Sondheim's Sunday in the Park with George at London's Barbican next summer. Her Wicked co-star Jonathan Bailey, who was also set to appear in the production, pulled out on Tuesday as well.
Addressing the audience at the end of the show, Grande thanked fans for their support, describing the experience as 'one of the most beautiful extraordinary' — the source text was cut off before the sentence completed.
