K-pop group I.O.I’s Yu Yun-jung (Starship Entertainment)

K-pop group I.O.I’s Yu Yun-jung will be joining another girl group Cosmic Girls as its 13th member, announced the singer’s management agency Starship Entertainment on Monday.

“We came to this decision after evaluating the synergy created between Cosmic Girls and Yu Yun-jung, and ask fans for their support for the new 13-member Cosmic Girls,” said Starship Entertainment in a press release.

I.O.I, which debuted in May, was created through Mnet’s reality K-pop group survival show “Produce 101.”

Formed by Starship Entertainment and China’s Yeuhua Entertainment, Cosmic Girls is a Korean-Chinese group that made its official debut in February with its first mini album “Would You Like?”

The group also stars on Mnet’s “Would You Like Girls: My Cosmic Diary,” a reality show featuring the offscreen lives of Cosmic Girls’ members.

Yu will fulfill I.O.I’s official schedule as originally planned, according to her entertainment agency.
