Hum, opinion?

It happened to me twice, I was glad of course but doubtful as it really is rare for someone to be compared to a...celebrity. It did happen today again. I was compared to Liza Minnelli (for looks of course).
I'm not as skinny as she was and my face isn't really that alike, but what do people see in me that reminds them of her? I really don't know, except for the nose, they are similar.
