Hawn -- known for hit movies like Overboard and Bird on a Wire -- gave birth to her only daughter on April 19, 1979; she split with musician husband BillHudson in 1980. The Cactus Flower star raised her children with partner Kurt Russell. When her little girl was born, doctors initially told Hawn she'd welcomed a boy. "I didn't know what it was. I just felt that it was a girl," she has said. "Then they said, 'Oh, no it's a girl!' And I said, 'What part of her anatomy were you looking at?'"
