At the karaoke, Kwanghee first started to sing a well-known trot song, "Who Cares About My Age," encouraging G-Dragon and Taeyang to join in towards the end. Following the trot performance, Kwanghee revealed that he's been wanting to sing songs like "Fantastic Baby," a hit number of Big Bang.�

To grant their partner's wish, G-Dragon and Taeyang started off the song, singing and rapping their original parts in the track, leaving Kwanghee with T.O.P, Seungri, and Daesung's parts.�

G-Dragon, however, cut the song short right at the peak and said, "This is good enough. I saw it. You're not that bad." Kwanghee then excitedly responded with, "I am pretty good with Seungri's parts." G-Dragon then quickly defended his maknae and said, "Seungri is good at singing. Our Seungri is really good at singing."�

Kwanghee then blurted out, "How could you do this to me and refer Seungri as 'our?' I thought we were friends." G-Dragon restated, "Our Kwanghee is good, but our Seungri is really good."�

Check out G-Dragon, Taeyang, and Kwanghee's surprising synergy on this week's airing of 'Infinity Challenge' above and below!
