Lucy Alexis Liu (Chinese: 劉玉玲; pinyin: Liú Yùlíng; born December 2, 1968) is an American actress who became known for her role in the television series Ally McBeal (1998–2002) and has also appeared in several notable film roles, including Chicago, Kill Bill, and the Charlie's Angels films.

She told Us magazine of her sexual encounter with a spirit. “I was sleeping on my futon,” Liu said, “and some sort of spirit came down from God knows where and made love to me. It was sheer bliss. I felt everything. I climaxed. And then he floated away. Something came down and touched me, and now it watches over me.”
