It’s no surprise Nicole Kidman is one of Hollywood’s most doting mamas. The beloved Big Little Lies star — who turns 52 on Thursday, June 20 — has opened up tons of times in the past about her journey through motherhood.

The Golden Globe winner is the loving mom of Sunday Rose, 10, and Faith Margaret, 7, with husband Keith Urban as well as adopted children Isabella Cruise, 25, and Conner Cruise, 23, with ex-husband Tom Cruise. “Whether you’re an adoptive mother, a foster mother, or a biological mother,” she gushed to Magic FM in 2014, “it’s the emotion of attaching to a child and helping guide them [that’s important].”
