19. Lily Tomlin
In a 2006 conversation with Metro Weekly, Tomlin said she liked kids plenty, but she and partner Jane Wagner chose not to raise their own:
“God only knows what I would have done with them, poor things. I really do like kids, but there wouldn’t have been room in my life to raise children. I was so involved with my career and I would have had to give up the career in large part because I could not possibly have shortchanged the child.”
