Los Angeles, March 17 : Actress Lucy Liu, who played the femme fatale O-Ren Ishii in Quentin Tarantino's cult classic 'Kill Bill', "didn't have a plan" and just "pulled the trigger" when she decided to become a single mum.

In an interview with The Cut published Thursday, the Shazam! Fury of the Gods actress, 54, said her decision to have son Rockwell, 7, who was born in 2015, was largely an unplanned endeavor.

"I didn't have a plan. I just thought, 'I want to change the conversation a little bit,' " she told the publication. "I didn't mull it over too much. I didn't do a lot of research, I just pulled the trigger."

"I can think myself out of something easily," she added. "If I think too much I won't do it. It's better for me to feel something and just go for it. A lot of people read books about parenting. I didn't do any of that. I was like, 'When the child is here, I'm just going to figure it out.' "
