2AM's Jo Kwon recently celebrated his 24th birthday and brought laughter to his fans once again with a silly photo.

Jo Kwon shared on his Twitter on the 28th, "Celebrating my birthday at the same place for 12 years!! A large-scale cone hat was made for me out of rolling paper!! I feel like I've returned to my trainee days >_< I love you - Wonder Girls, have a safe trip to the U.S.!!! Be careful of the typhoon," along with the photo above.

The photo shows Jo Kwon wearing a large, decorated cone hat while holding a birthday cake. It seems the Wonder Girls and Jo Kwon had gathered in the practice room to celebrate to reminisce on past memories while spending time together before the girls' trip back to the States.

Fans commented, "Happy birthday", "I wish you the best", and "It's a heartwarming friendship."

Happy Birthday to Jo Kwon!
