We previously reported that VIXX will be making a special cameo on SBS' 'Heirs', and it's now been revealed that they'll be appearing as themselves! On the upcoming 4th episode, VIXX will play themselves at the concert for Bona's (f(x)'s Krystal) father's label, Mega Entertainment. VIXX were able to score a cameo after Hongbin caught the eyes of the 'Heirs' PD. The boys impressed the staff on set by completing their rehearsal and filming in one take. Catch VIXX on 'Heirs' later today at 9:50PM KST!
