‘Bloom’, which was released on May 22, 2012, will have a concept of “blossoming” that will complement and focus on the singer’s feminine qualities. The album will be a more mature type of femininity.
G.NA has actively participated in putting this new album together, helping to write and compose some of the songs. Her title track “2HOT” written by hit-makers Kim Do Hoon, Lee Hyun Seung, and Choi Gab Won consists of an electronic sound, and the brass along with the deep bass help tie the dynamic sound together. The singer collaborated with singer Jay Park for the hip-hop track “Green Light“, a song where two individuals attracted to one another play hard to get. G.NA also released an English version of her first #1 hit “I’ll Back Off So You Can Live Better” on this album, and it features Beast‘s Yong Jun-hyung.
On May 20, 2012, a teaser for the album's title track "2HOT" was released through G.NA's official YouTube channel and on May 22, 2012, the music video for "2HOT" was released.
