Boom couldn't help but become flustered during a recent recording that took place when another celebrity brought up a past clubbing incident.

MBC has a new variety show called 'Extreme 7' and during the recording of the upcoming episode, one of the celebrity guests commented that he had seen Boom 'disappear' with a non-celebrity woman at a nightclub around 3AM. He further backed up his claim by revealing details saying that a comedian 'P' had also been spotted at the club.

This obviously had Boom quite flustered and the other stars started to question him about this testimony, leading to a lot of amusement and embarrassment from Boom. After taking a short break from filming, Boom apparently opened up and explained how this particular situation had unfolded.

In order to catch Boom's full story, you'll have to tune into 'Extreme 7' airing at 9PM KST on the 27th to find out!
