Black holes, atoms, and infinite density

Does the center of a black hole necessarily consist of a singularity? I don’t think there’s anything that says the density must be infinite, just that it’s sufficient to prevent light from escaping. There’s a big difference (I think) between “sufficiently dense as to have an escape velocity > c” and “infinitely dense”.

IANAP but I read an article that said it depended on how gravity actually works as to whether you get a singularity or not. In some models you get a black hole but you don’t get a singularity.
