The 45th Earth Day was celebrated in Washington last Saturday, April 18, with a star-studded outdoor concert. For fans of K-pop, the Global Citizen 2015 EARTH Day had invited male group VIXX and soloist Roy Kim to perform and represent Korea at the event.
It appears that VIXX was particularly excited to meet international superstars Usher and will.i.am, who they snapped a few group photos with backstage.
Hyuk and Hongbin kept the meeting professional by gifting Usher with a signed copy of their latest album, while member Leo used the special opportunity to take a selfie with the Black Eyed Peas leader.
Meanwhile, the Global Citizen 2015 EARTH Day event brought together numerous popular acts, including Fall Out Boy, No Doubt, and Mary J Blige.
