The new boy group GOT7 held a debut celebration with their senior singer 2PM's member Taecyeon.

Yesterday, GOT7 posted on their Twitter, "Who is the surprise visitor who came to our practice room with a debut celebration cake? Taecyeon who came to see how good-looking GOT7 really is! Thank you" along with two pictures.

In the pictures, GOT7 members are in stage outfits and makeup and Taecyeon is in a casual outfit. They are holding up a cake and posing for the camera together.

Internet users who saw this commented, "Congratulations on your debut," "Taecyeon is like their older brother who takes care of them," etc.

JYP's new group GOT7 debuted on January 16.
