With his holiday concert 'All Night Stand' fast-approaching, there is only one grave matter on Psy's mind: which female artists he will parody. 

Recently, the singer uploaded a post on Twitter that read, "I'm seriously debating which female artist to parody." 

Fans who saw the post responded with, "Show us 'Up & Down'! We'll go see it," "We recommend EXID's 'Up & Down,'" and, "He can dance 'Up & Down.'" Seems like a lot of people really want to see Psy pelvic thrusting on stage during the holidays! There were others who suggested that he parody IU's "Zeze" controversy, commenting, "What about doing an IU parody which is hot right now," and, "I think he will do a 'Zeze' parody."
