Photos of 'Superstar K4' contestants Roy Kim and Jung Joon Young on the set of a commercial have caught the eyes of fans.

Although other contestants from the audition program also participated in the commercial as well, most netizens seemed focused on the appearances of none other than this season's heartthrobs, Roy Kim and Jung Jun Young.

As revealed in the photos taken on set, Roy Kim can be seen wearing a plain t-shirt and holding his guitar, while Jung Jun Young shows off his own unique fashion sense sporting a leopard print tie.

Meanwhile, both contestants passed the most recent round of competitions on the 19th. They'll be performing on the October 26th broadcast of Mnet's show�in hopes of getting one step closer to their dreams.
