Celebrate the big 2-1 with a childhood "treasure"! Got7 member JB became legal around the world yesterday. To commemorate his new age, the When A Man Loves actor decided to reminisce about the good old carefree days of childhood. He shared the adorable photo on Instagram with this caption:  "A treasure I found at home."

Over 73,000 fans instantly liked the cute image, and some posted sweet birthday messages.

Got7 embarks on their Asia tour this month. They will travel to Shanghai, Hong Kong, and Taiwan among other locations. Their Korean-Chinese online drama titled Dream Knight premieres on January 27. 

Happy Belated Birthday to JB!
