Yes. Celebrities were spreading photos of fires on other continents and other years and claiming that it was the end of the world.
Their apologists will claim they were "just raising awareness" or "drawing attention to the tragedy," but in reality they're doing more harm than good.
Interesting, I think that climate change, slash and burn agricultural practices on marginal land, and the inability of the biome to re-establish itself is what is doing the harm. I never even once gave a single thought to what "celebrities" or other people that were wrong are saying, just like how I deal with right wingers that deny climate change is occurring.
And I would argue that it's hard to overstate the harm of global warming, so a few ignorant celebrities being incorrect against the mountains of well fund misinformation is not doing more harm than good. They are wrong on the scientifically correct side of the issue, and that matters. They are unlikely to cause harm to anyone, like climate change denier or Jenny McCarthy on vaccines.
