2AM's member Jo Kwon turned into a man.

Today, Jo Kwon posted on his Twitter, "It's hot" and "Summer is here..." along with two pictures.

In the pictures, Jo Kwon has shorter hair and is wearing a black tanktop with sunglasses.

Through his sleeveless shirt were seen his buff arms with tattoos.

Internet users who saw this commented, "Men's changes come from hair," "Wow he's a man now~," etc.
