According to the Myheritage app, I look like Jolin Tsai, Ayumi Hamasaki, Ai Otsuka and Kyoko Fukada – which is odd on all sorts of levels, the most obvious ones being that they look nothing alike and I'm not asian.
The person people actually do tell me I resemble – which I don't, btw – is Audrey Hepburn. I've had total strangers tell me this, and I look about as much like her as I do Jolin Tsai, which is to say I look nothing like her at all.
I did have a woman on a bus ask me if I was Sara Gilbert once. This is the only one I can see any slight resemblance with, and even at that, there's not much similarity.
