2011: Formation and debut with Trouble Maker[edit]
In November 2011, Cube Entertainment labelmates Hyun-seung (former member of Beast) and Hyuna (former member of 4Minute and Wonder Girls) formed the duo Trouble Maker.[1] Hyuna had previously released two singles, but both described the sub-unit as something different to either of their respective groups. The sub-unit was officially billed as 'JS & Hyuna', which Hyun-seung went on to reveal on his Twitter included his new stage name for the subunit, Jay Stomp.
On November 25, the unit started revealing teaser photos for the album, revealing a private-party concept.[2] The duo also gave a teaser performance at the 2011 Mnet Asian Music Awards, which included an on-stage kiss.[3] The duo's first mini-album and single, both eponymously titled "Trouble Maker", were released on December 1, 2011.[4]
The duo's live performances of "Trouble Maker" on weekly music shows were criticized by the Korean media for their sexually suggestive choreography. In response, Cube Entertainment altered the choreography for the rest of the promotion period of "Trouble Maker".[5] The duo also performed "Trouble Maker" at the United Cube concerts in London and Brazil in December 2011.[6] Trouble Maker went on to win the triple crown on M! Countdown for "Trouble Maker".
In October 2013, Cube Entertainment confirmed Trouble Maker's upcoming comeback with a racy photoshoot.[7] On October 28, the group released the single "Now" from its ChemistryEP. The single's music video, which drew inspiration from serial criminals Bonnie and Clyde, earned a 19+ rating for its heavy references to sex, alcohol, and cigarettes.[8] "Now" had the highest score ever recorded on music show Inkigayo, maxing out at 11,000 points.
2018—2021: Departures from Cube Entertainment[edit]
On September 13, 2018, Hyuna was announced to have been removed from Cube Entertainment alongside Pentagon's E'Dawn, following the announcement they had been dating.[9] The next day, Cube withdrew the decision due to severe backlash from fans and a drop in stocks, and announced they would further discuss it with the two. On October 5, it was announced Hyuna would end her contract with Cube due to Cube's previous violation.[10]
On August 2, 2021, Hyunseung also left Cube Entertainment.[11]
