We left someone out of the amazing Idol Big Show line up and that is Lee Seung Gi! The ballad singer who returned with a new album recently is going to be one of the performers at the Idol Big Show. But here's the real exciting thing to look forward to: He will show his dance moves! We get to always see him perform slow songs, always. He does not dance and this is our chance to finally see him move to the beat! He will also perform a song on his 4th album, "Love is..." G-Dragon will perform "Hello" with Dara and Big Bang will make an appearance. 2NE1 will perform a different version of Fire as well as "Let's Go Party". After School will transform into the Pussycat Dolls and sing "Buttons" as well as perform other girl groups' dances such as Brown Eyed Girls' Saucy Hip Swaying move. The girl groups that are present will have a dance battle where Yuri, SooYoung, and HyoYeon of Girls' Generation will flaunt their powerful dance moves, Kara will show a dance sexier than their Butt Dance, and 4minute will perform a dance with no shoes and miniskirts. To top it off, HyunA will move to Beyonce's "Deja Vu". Are you psyched or what? Idol Big Show will air on the 3rd of October through SBS. Bonus picture below.
