Starship Entertaiment has released member profiles of three more members of their soon-to-debut girl group Cosmic Girls.

On Dec. 25, photos of three new members, named Seol A, EXY, and Soobin, were uploaded on the official social media pages of both Starship and Yuehwa Entertainment.

These three members will make up the "Sweet Unit" sub-group, the third addition to the two previously revealed "Joy Unit" and "Wonder Unit" subgroups. 

This subunit is meant to be full of members who are sweet, but gentle, hence the name "Sweet Unit." 

This is the first of the revealed sub-groups to not include any Chinese members.

EXY was previously known to be a Starship Entertainment trainee and was featured in Unpretty Rapstar Season 2. She joined on the sixth episode, but was eliminated by the eighth.

The fourth and final sub-unit will be revealed sometime in the near future. 

Meanwhile, the group is aiming for a debut sometime in the first half of 2016. 

Cosmic Girls was formed by a joint contract between the Korean and Chinese agencies Starship Entertainment and Yuehwa Entertainment. To better promote in both countries, the group is comprised of both Korean and Chinese members.
