The Big Little Lies star has been very candid about her struggles with infertility. The actress has been married twice, previously to Tom Cruise and currently to Keith Urban. Early in her marriage with Cruise in her twenties, Kidman suffered a traumatic ectopic pregnancy, which led to the couple's decision to adopt their two children, Isabella and Connor. She later suffered a miscarriage at the end of her marriage to Cruise.
When Kidman married Urban she thought she'd be unable to conceive naturally, but gave birth to her biological daughter, Sunday Rose, in 2008, when the Australian actress was 41 years old. Kidman has never discussed whether or not she used IVF to become pregnant, but in a 2012 interview with Australian magazine Who, reported by The List, she explained, "I've done all the stuff you can possibly do to try to get pregnant. So, the way it just happened with Sunday was like, 'What?' The percentages were so low. It is the miracle in my life."
Three years later, Kidman and Urban welcomed their second biological child, Faith Margaret, via surrogate. Despite a tumultuous pregnancy journey and four children, The Sun reported that Kidman said she would still love to have more children. Getty Images
