2AM's Jo Kwon uploaded a picture of his bare arm with a henna tattoo on his Twitter. On the 5th, he uploaded this picture and wrote, "I got an I AM henna on my shoulder. haha" Though the things he has on his arm look like symbols, it does say "I AM," which is the name of 2AM's fan club. Fans commented,

"It's nice to see another side of him." "He wrote his fan club name...only Jo Kwon would!"
