Kerry Washington: Jan. 31
If you're one of the many people who turned the big 4-0 this year, you're not alone. This Is Us costars Milo Ventimiglia and Justin Hartley both hit the big milestone this year, as well as musicians Kanye West and Chris Martin. In addition to sharing the same birthday, John Cena and Kal Penn also turned 40 along with Tom Brady, Jessica Chastain, and Liv Tyler. If we didn't know any better, we'd say these stars have found the fountain of youth.
