3. Uma Thurman
Uma Thurman had her third baby, Rosalind Arusha Arkadina Altalune Florence Thurman-Busson, in July 2012 at 42 years old. While it's a mouthful, they call her "Luna" for short. She welcomed her new bundle a decade after having her son, Levon, and 14 years after her daughter Maya Ray, who she had with her ex-husband Ethan Hawke.

When asked if re-entering motherhood again was hard, her answer was frank. "No – it’s very interesting actually. Everything feels new.”
