If your favorite Korean idol was born 20 years ago, then they are now officially considered to be an adult in South Korea.

On the third Monday of May, 20 year olds celebrate Coming Of Age Day, which means that several idols are celebrating the day. 

Some idols thanked their fans for their support on their SNS.

2NE1's Minzy posted a picture on Instagram, where she was seen holding a bouquet. "I didn't know tomorrow is my Coming-of-Age Day. My Fans gave me some beautiful roses. and gifts. and who's gonna kiss me on my cheek?"

4Minute's Sohyun also tweeted a fan art picture that was wishing her a happy Coming Of Age Day, and thanked several fans directly for their support. 

Some of the idols who are celebrating their Coming Of Age Days are EXO-K members Sehun and Kai, B.A.P's Youngjae, f(x)'s Krystal and Sulli, miss A's Suzy, and BTOB's Ilhoon.

Also celebrating this milestone are former Kara member Jiyoung, Boyfriend's Jeongmin, A-Pink's Naeun and Yookyung, Girls' Day's Haeri, Teen Top's Niel, and many, many other idols; the list could keep going and going. 

Even though the idols have very busy and hectic schedules, hopefully they'll be able to take a few moments to commorate the fact that they're now legal adults in South Korea.
