Taylor Swift and Ariana Grande have both issued stern messages to their legions of young fans, urging them to take the coronavirus pandemic more seriously.
In a message posted to her Instagram story, Grande said the way some people were choosing to handle the outbreak was "incredibly dangerous and selfish".
"I keep hearing from a surprising amount of people statements like 'this isn't a big deal, we'll be fine, we still have to go about our daily lives' and it's really blowing my mind," she wrote.
"I understand if that is how you felt weeks ago, but please read about what's going on. Please don't turn a blind eye.
"It is incredibly dangerous and selfish to take this situation that lightly."
The 'Thank U, Next' singer, who has millions of fans who are teenagers and younger, said the "'we'll be fine because we're young' mindset" was putting more vulnerable people in danger.
"You sound stupid and privileged and you need to care more about others. Like now."
Taylor Swift's social media shared a similar sentiment with a message that pleaded with fans to "make social sacrifices".
"Guys - I follow you online and I love you guys so much and need to express my concern that things aren't being taken seriously enough right now," Swift wrote.
"I'm seeing lots of get-togethers and hangs and parties still happening. This is the time to cancel plans, actually, truly isolate as much as you can
"Don't assume that just because you don't feel sick that you aren't possibly passing something on to someone elderly and vulnerable to this.
"It's a really scary time but we need to make social sacrifices right now."
