Ariana added a sad-faced emoji for extra expression of her disappointment in sharing the news.
"I'm so so sorry. There is nothing I hate to do more than to do this but I promise to make it up to you in the future.
"I love you and thank you for understanding."
Grande kicked off her Dangerous Woman World Tour in February of this year.
Immediately following her May 22 concert in Manchester, a suicide bombing took place outside of the arena, resulting in 23 deaths and at least 59 other injuries.
Grande postponed a handful of tour dates before bravely continuing with the trek across the globe.
If Ariana recovers in time, her next show will take place on Saturday in China before she heads to New Zealand and Australia in September.
