Jo Kwon turned 23 on August 28 and he celebrated his special day with an adorable selca.

The 2AM member posted a photo taken with his little puppy on Twitter with the caption, “Heart Fluttering.” In the photo, Jo Kwon is seen wearing suspenders and a bow tie, making a funny facial expression with his hair rolled up (see top photos).

Moments later, he uploaded another photo (see below) on Twitter with the message, “Having my birthday party at the same place for 12 straight years!! They made a giant birthday hat out of rolling paper!! It feels like I’m back to being a trainee >.< I love you all – Wonder Girls have a safe trip to the U.S.!! Watch out for the hurricane T.T.”

His photos have drawn celebratory messages from netizens who in particular took notice of Jo Kwon’s almost doll-like image.

Netizens commented, “Happy birthday Jo Kwon!” “Why does he look like a girl?” and “Is it just me, or does he look really feminine in this photo?”

Happy birthday Jo Kwon!
