Smart announced the birth on her Instagram account Monday with a picture of her holding new daughter Olivia as husband Matthew Gilmour looks on.
In 2002, the 31-year-old was kidnapped at age 14 from her Salt Lake City bedroom by street preacher Brian David Mitchell and held captive for nine months. Mitchell was sentenced to life in prison for kidnapping and raping Smart.
Smart, who has become a child safety advocate, spoke out against Barzee’s release. But she has said she won’t let it stop her from living her life.
