Ok. I was on tumblr one day and then I saw a post with Big Bang's English names. Check this out

G-Dragon (Jiyong Kwon)- Jack Kwon (Aww that's cute :D)

T.O.P (Choi Seunghyun) - Spencer Choi (Wtf XD I'm dead)

Taeyang (Dong Youngbae)-  Tyler Dong (Tyler? I thought Taeyang's name was like Tyrone or something cause he wanna be black but you need to be grateful)

Seungri (Lee Seunghyun) - Steve Lee (Lol Steve. *robotic monkey voice* STEEEVEE~)

Daesung (Kang Daesung)- Dylan Kang (Dylan... Like Dylan O'Brien aka Stiles from Teen Wolf)
