EXO's Baekhyun, whose real name is Byun Baek Hyun, made his transformation from a Kpop idol into an actor in the SBS historical drama, "Scarlet Heart: Ryeo." Recently, co-star Lee Joon-Gi, 34, revealed Baekhyun is the energizer on set.

On Sept. 5, a brief preview of MBC's "Star Show 360's" pilot episode featuring the nine-member South Korean boy group EXO began streaming on the web. In the short video, Baekhyun showed why he is one of the most beagle-like idols around by making adorable faces to the camera.

Much to the surprise of many, the "Scholar Who Walks the Night" star sent a video message in support of EXO's Baekhyun. Affectionately calling him "Hyun-ie," Lee complimented the Kpop idol as he revealed that Baekhyun is the energizer on set.

"I hear that I am an energizer a lot as well," said Lee. "But Hyun is someone who will inherit that position from me."

Lee then revealed Baekhyun prepared a lot for his guest appearance on MBC's "Star Show 360," stating that the latter apparently wanted to make the viewers laugh through singing and dancing. Impelled on by Lee's thoughtful words, Baekhyun reportedly makes the studio break out into laughter when he parodies Lee Jung Jae's signature lines from "Assassination" and "Brand New World."
