Actor Jang Dong-gun made an appearance in rookie band Le Ciel’s teaser image for its debut single.

The image, released by Demn Tiger on Tuesday, shows a close-up shot of Jang’s face.

Jang reportedly decided to pitch in on the new project, due to his acquaintance with Le Ciel’s producer.

Jang also had a cameo appearance in the teaser video for Le Ciel’s debut single “Thank You So Much.”

The group is slated to debut later this month.
