On Thursday, STELLAR's founding members Gayoung and Jeonyul officially said goodbye to the girl group after six years.
The pair shocked fans last week when they announced that they would be leaving STELLAR once their contracts expired on August 31.
They wrapped up their activities with the group earlier this week with a special 6th anniversary concert in Seoul called Interstellar: Time Travel Through 6 Years, before heading to Tokyo to complete another concert.
STELLAR's agency has since announced the addition of a new member Youngheun. This follows Soyoung's addition in May for the group's "Archangels of the Sephiroth" comeback.
The agency also revealed that STELLAR would continue on as a four-member group with the two new members replacing Gayoung and Jeonyul.
There was some controversy over the weekend following Youngheun's addition to STELLAR.
STELLAR debuted in 2011 with "Rocket Girl." They peaked in 2014 with "Marionette," which reached No. 35 on the Gaon Digital Chart and went viral for its sexy music video and choreography.
The group has since turned to crowd-funding from fans to pay for their comebacks. Their last project broke a record on crowd-funding platform MakeStar after pulling in over $94,000.
