– G-Dragon was spotted with yellow hair.
– Daesung’s eyes are small and cute
– They went to the (Las Vegas) Strip.
– Taeyang is short like 5″4′

– T.O.P still sporting his white hair.
– They were able to get autographs but not photos.
– Their manager was nice but won’t allow them to take pics.
– They were spotted at the Bellagio but “they’re staying off the strip on Charleston and Arville”
