"Hello Bitches" is the second digital single by CL. It was released on November 21, 2015 as a free-to-download track on SoundCloud, and on digital platforms the next day.
About the song, CL said that "It's not an official single but more of a street single. I wanted to give a little surprise video to excite the fans who have been waiting while I prepare for my solo album. Since I am Korean, it's a good way of presenting me and it's for everyone around the world to see where I am from and to keep it authentic."
