from stalkingfraud at Soompi:
the information on the baby was out. hes 4 in korea and turning 5. yes, hes a bit old but i guess thats the concept
that they'll be doing.
no other information is released so we'll just have to wait!
+) one of my best friend is at korea now and she just called me from music bank rehearsal saying
'hello baby' is CONFIRMED because key is with the baby and he told the fans,"this is my son".
