Singer Brian Joo made a surprise transformation into Lady Gaga for his latest performance on 'Immortal Song 2'. For this upcoming week's broadcast of KBS 2TV's 'Immortal Song 2', Brian was challenged to sing Jung Hoon Hee's "That Person Is Stupid". For his remake, Brian added a strong dance beat to give the song a fresh, clubbing feel. Brian revealed, "This stage will see a male version of Lady Gaga. I will show you some real club music." For his performance, Brian wore Lady Gaga's signature rhinestone-studded sunglasses and a leather jacket. He also brought up back-up female dancers and a rapper, resulting in a stage that electrified the audience. Afterwards, Jung Hoon Hee gave him a round of applause, saying, "I was able to feel your youth and it was a very exciting stage." Brian's colleagues (who were backstage) stated, "It was a fitting stage for Brian" and "It was such a colorful stage".
