YG Entertainment has announced that its new girl group Rebelle will be debuting in January 2013.  

CEO Yang Hyun Suk revealed, “YG Entertainment’s new girl group will debut into the music scene in January of next year. G-Dragon is in charge of the overall production of their debut album. But since he’s promoting his own solo album, the debut date was pushed back a bit. On top of that, Epik High will make their comeback and LEE Hi will debut this month. 2NE1 and Taeyang will be releasing their new songs in November, so the new girl group will be debuting next year in January. Another reason January was chosen is because we wanted to start YG’s new year with the new girl group.”

Seven girls have been introduced to the YG family, and are currently training hard for their debut and future music career. The CEO has commented on how these girls are extremely hardworking "At YG we only expect hardwork. Blood, sweat and tears. If they don't want to sacrifice long training hours and strict conditions then they don't belong with us. It's as simple as that. My new group, they exceed expectations and the first thing that entered my mind when I saw them working hard for their dreams was that they're going to make it big. I can promise you that"

Regarding who is in the group is very much confidential. Revelations on who was going to be in the group, such as Jenny Kim has been diminished instantly by Yang Hyun Suk,

“An existing member who was previously revealed to the public has already left YG’s new girl group,” increasing curiosity about the group’s final members.
