I don't know much about the production seeing as she kept it a secret just like the guys but she showed us all in the day it dropped because she was so excited. Before she decided to pursue her real passion of design and fashion, she was very eager to try her hand at music and singing. So she paired up with twenty ten (sense she was already very good friends with them) and they made that song.
oh, cool!! I think it was still cool that she tried dabbling with music, and I'm glad she was so excited about it!! It's always good to hear someone was happy to be part of the production of something amazing.
