WINNER fans, get your party hats ready because it's Kang Seung Yoon's born day and it is trending worldwide on Twitter!  The singer came into the world on January 21, 1994, making him 22 internationally and 23 in Korea. It's also singer Kim Ye Rim's birthday, who was born on the same date and in the same year as Kang Seung Yoon.

Everyone in K-Pop seems to be growing up so fast! Makes us wonder, where does the time go?

Be sure to wish the two artists a very happy birthday!
