Sienna Miller, the 21 Bridges actor, is expecting her third child, her second with boyfriend Oli Green, with whom she also has a 2-year-old daughter with Oli, and 13-month-old son with ex-boyfriend Tom Sturridge. In an interview with Glamour, Miller revealed that expanding her family in her 40s has transformed her life, allowing her to become a more grounded human. She also revealed that she froze her eggs to increase her chances of having another baby. Miller believes that getting pregnant and being older together is a "biohack" that allows for more women to get pregnant and enjoy their children.
