Keena, a member of girl group Fifty Fifty, left for the U.S. to attend this year's Billboard Music Awards slated for Sunday. 

The quartet earned fame with their hit song "Cupid," which is nominated in the Top Duo/Group and Top Global K-pop Song categories at the annual U.S. awards show.

Keena is the only member attending the show as her bandmates are currently on hiatus due to a contract dispute with their agency.
