The fan also claimed that Braun, whose other client is Justin Bieber, had orchestrated his engagement to Hailey Baldwin.
Grande disputed the fan's theory and wrote, "You do realize we are human beings who love and have lives, right? And that Scooter is a wonderful human being too who cares first and foremost about our health and happiness?"
"Love is lit. S**t happens. I hope to god it happens to you too. You deserve it," she added.
In response to another fan's joke about her manager, the 25-year-old popstar said Braun is "wonderful and very human. Always puts his artists' health and happiness first".
