Do (some) Halflings have pointy ears like Elves?

I was under the impression that Halflings in D&D look pretty much like little humans.
But when I browse online concept art and fan art, I see a lot of Halfling images with Elf-like pointy ears… and it isn’t always clear which art is canonical and which isn’t.

So: In D&D, do Halflings (or some types of Halflings) have pointy ears akin to Elves?

Even if they generally don’t, are there exceptions?
If it depends on the D&D version or campaign setting, which ones exactly?
