The answer is Yes, but no not really.
The reason that nothing can be a completely perfect circle is that in mathematics we can define the degree of perfection of the circle to any infinite degree of accuracy that we choose. So perfection in geometry is perfection like there is no other perfection in the universe.
When it comes to nature, which I interpret as "something that exists naturally in the physical world," our ability to measure is governed by very finite, preposterously finite scales compared to the theoretical perfection of geometry. So even if there were something that was a perfect circle in nature, it would be impossible to prove it, by inherent limitations of measurement and verification.
However, I argue that humans exist in nature, and that the human mind is a part of nature, along with all of our ideas.
So the only perfect circle in nature is the one in your mind.
(As regards the whole soap bubble idea, remember that the circumference of the circle would be made by irregular rows of moving, flowing, vibrating water molecules along with the molecules of whatever surfactant you used to make the bubble. Anyways I'm just sayin' that that's far from perfect. )

Actually, there are many "perfect circles," but the operational word here, I believe, is "completely" which then changes things, simply because of the distortions or minor aberances caused by OUTSIDE forces... nothing exists within a "vacuum" because nature abhors it! One thing is for sure, "iff," there was absolutely NO air movement, and the water on a pond's surface were like glass, and only one drop of water hit the surface of that pond that had absolutely no particulates or polutants or water bugs etc., "thenn" I imagine the conditions MIGHT be right for a competely perfect circle to result from the aftermath of the droplet's impact.

No. Aperfect circle is an ideal that can be approached to any degree of accuracy but never achieved

An equatorial cross-section of a neutron star probably qualifies.

The event horizon of a black hole is perhaps a perfect sphere.
