Back on mid-January, project band OK PUNK released their digital single "Ugly", a punk rock arrangement of 2NE1's hit song. After approximately two months, Mnet released a music video for the track which features various cuts from the group's reality show "Kim Okbin's OK PUNK."

OK PUNK's self-titled debut mini-album contains four tracks including "Ugly" and an instrumental. The band previously released a music video for the single "Not The End" off of their mini-album.

OK PUNK is led by actress Kim Ok Bin along with Devin of N.E.X.T, The KOXX's vocalist Lee Hyun Song, BandToXic's drummer Kim Seul Ong, Dickpunks' keyboardist Kim Hyun Woo and vocalist and synthesizer of Go Go Star, Lee Tae Sun.
