Hyosung and Yubin, formerly of SECRET and Wonder Girls, respectively, are coming together to create their own project duo.

Hyosung's agency confirmed the news on April 13 KST, stating: "Hyosung is forming a project group with Yubin. It's still in its early development, so details like when they are going to release a song have not been set."

The two idols are long-time friends, who were first supposed to debut together under Five Girls, a 2007 girl group that also included a pre-debut G.NA, Spica's Jiwon, and UEE.

Meanwhile, since leaving their respective girl groups, Hyosung has been active not only as a singer, but as a drama and variety star, while Yubin founded her own entertainment label.

Stay tuned for more about this exciting collaboration!
