The 43-year-old actress, who has previously dated actor Will McCormack and screenwriter Zach Helms, said that since she spent so much time believing she was not pretty, she now unknowingly falls for guys who sing her praises - even if they are no good for her, reported Us magazine.
"I find that if somebody finds me beautiful, it melts my heart because it's not something I heard most of the time growing up ever. I can easily be enticed into some terrible relationship because I'm like, 'Oh, my God, you think I'm beautiful?" Liu said.
The actress, who was raised in Queens, New York, said that her mother had cut all her hair off, because of which she was not considered feminine at all.
"I grew up as a tomboy, and if you've seen photographs of me as a child, you see my mother cut all of my hair off. I had no hair... I was not considered feminine at all, and boys did not look at me. I was a toothpick," she added.
