However, due to their busy schedules and far away locations, it appears neither were able to join in on the fun too much.  Girls' Generation appeared on a small TV screen for a few seconds at around the 2:13 mark while Psy made no appearance, but his "Gentleman" song is prominently featured in the video.

After having the most viewed video in 2012 (including all-time on YouTube) with "Gangnam Style", Psy once again enjoyed having the most viewed YouTube video in 2013 with "Gentleman". Girls' Generation also celebrated by winning 'Video of the Year' with "I Got A Boy" at the YouTube Music Awards.
