"You should match the number of Australian streams and donate the money to those affected by the Australian Bushfires," one person wrote online.
"Enough about #yummy, can we see you make a real difference and donate to the Australian bushfires happening RIGHT NOW?" another wrote.
"You probably own 20 cars now instead of paying for an extra y not think of the people who have lost their homes in the Australian bushfires you need 1 car don’t be greedy sell them and donate," another fan mused.
However, Justin isn't the only celeb copping it from fans for their lack of donations.
Earlier this month, Kim Kardashian was heavily criticised for not sending any funds to Australia.
"Nothing gets me more heated than to see the Kardashians/Jenners talk about climate change/wildfires & not donate even a penny," a fan wrote after all the Kardashians' posted about the devastation on their stories.
"Nothing gets me more heated than to see people think they know what we donated to and to think we have to publicize everything," Kim tweeted back.
If you would like to help with the Australian bushfire relief, you can donate to one of these charities:
- Victoria Country Fire Authority
- Australian Red Cross Disaster Relief Fund
