Unfortunately, despite the star looking amazing, some people thought that it was the wrong time for her to be posting such a thing with the riots that are going on in the US Capitol right now.
However, despite some people having a problem with the timing of her post, Wilson was also receiving a lot of praise for focusing on her health, calling her an "inspiration".
"You are my idol, you've come on long way sweetie and you have a strong willpower," wrote one fan.
"Miss Wilson - You should be EXTREMELY proud of your inner strength, determination and commitment to become even more healthy!" said another.
"Thank you for the ongoing inspiration @rebelwilson you've helped me greatly to stay the course to better health," a third commented.
In 2020, Rebel set a goal to reach 75kg, a goal she reached before the year was out.
"Hit my goal with one month to spare!" she wrote in November. "Even though it's not about a weight number, it's about being healthy, I needed a tangible measurement to have as a goal and that was 75kg."
