January 14th is my birthday. Nobody that I know of, lol. Jason Bateman?
Off the top of my head, I share a birthday with Alex Faust who is the current play by play announcer for the Los Angeles Kings of the NHL. He doesn’t appear in the list of famous birthdays. It’s just one special thing I remember.
I remember learning that I shared my birthday with Pope John Paul II while watching his funeral procession on TV in April 2005. I didn't learn it from the TV though; my friend's younger sister sent all of our birthdays to a text service that responds with who you share it with. They both laughed when my result came back!
Aside from him some notable ones that have stuck in my head as useless knowledge: Chow Yun-Fat, Tina Fey, Brandon Reilly (Nightmare of You), and Taeyang (BIGBANG).
There was a YouTuber I began following ages ago who did lots of fashion, makeup, and hair styling videos. She became so popular that she received a modeling contract in Japan, and she still does modeling/media work currently there. At some point I was looking at her Instagram and saw we've the same birthday.
I know of k-pop idols I share a birthday with, namely Kang Seulgi and Choi Sooyoung and also that one LOONA girl. But for western celebrities I had to google, and pretty much only recognized Emma Roberts and Vic Fuentes
