Seventeen has revealed the latest member and it's Shin Dongjin!
He was born in 2000 and it looks like we finally broke the millennium wall for their birth year! Don't be fooled by his age though - this latest member was encouraged by his friends to apply for a modeling contest where he came in first place.
Despite his young age, he is very mature and went through the tough process of training.
Make sure to look forward to the rest of the members!
