K-pop star Sowon, a member of the popular all-girl group GFriend, is under fire for posing with a mannequin decked out in a Nazi uniform, according to reports.

The 25-year-old performer, whose real name is Kim So-Jung, posted since-deleted photos on Instagram showing her affectionately standing next to the mannequin — forcing the group’s record label to issue an apology, according to a report in the Independent on Monday.

“We would like to offer a sincere apology for the issues caused by video clips from the behind-the-scenes footage of GFriend’s comeback show as well as photographs uploaded by GFriend member Sowon,” Source Music said in a statement.

“We would like to apologize for failing to recognize prior to the shoot that there were inappropriate props located on the [premises], neglecting to carry out a careful review of the footage and photographs before uploading them, and failing to maintain sufficient awareness of issues with vast historical and social implications,” it said.

The company went on to say that Sowon felt “a profound sense of responsiblity and deep regret” for posting the pics — which she “immediately deleted.”

The images were from a video shoot and were posted with behind-the-scenes clips in December and on Instagram on Sunday, the Independent said.

GFriend, a six-member group formed in 2015, has released four studio albums and completed two tours of Asia amid wide acclaim, according to the Sun.

Sowon has 817,000 Instagram followers.
