YG Entertainment and SM Entertainment have both announced that Quiet Legends and Rebelle are to collaborate. 

 SM Entertainment founder and Chairman Lee Soo Man revealed that his latest boy band Quiet Legends (whose debut is still unknown) will definitely be having a collaboration with YG's Rebelle. "We have two power groups that will both start the year and how else could we utilize it than putting two and two together?" 

CEO Yang Hyun Suk revealed, “I have to admit, when the teasers for these boys came out I knew that they were going to be the IT group in 2013 but so is my group, Rebelle. They'll dominate the year and following years and why not add a bang to that by collaborating with Quiet Legends? It seems only logical" 

Nothing else yet has been revealed about the future collaboration.

For the past few weeks, SM has been releasing images of their boy band members, introducing each one of them properly in a week.
