These first 2 photos are from backstage at the “QQ Awards” in China. The original poster (seen in the first photo) was covered up with stickers, and had his username removed, without permission. Then the photos were posted by another user (who has since removed them and changed her username) claiming they were her photos. She has since removed them, since we only have the one G-Dragon image unedited and not both, we left the edited one up as well so VIPs can see all the pictures, even if they are edited.
The third photo was taken at Big Bang’s fan meetings in China. Here Big Bang is posing with the cosplay winner at the Changsha fan meeting.:
