I don't think 'Golden Tiara' gets all that big. I do think the picture with the cat in your other thread looks like 'Golden Tiara,' and the scale seemed about right to me, but I agree with CJ that this one doesn't at all. 'Golden Tiara' has no dimpling that I've ever seen, and this plant does. The leaf shape is more rounded on 'Golden Tiara,' as well. Cordate, perhaps, but not as elongated as those leaves look.
This actually looks much like the hosta recently identified for me as fortunei Aureomarginata.
