On July 3 episode of JTBC's television show 'Knowing Brothers', the members of 2PM joined the talk.

Ok Taec Yeon said, "There was this time when we went to perform in Singapore. I happened to experience something so terrifying in my hotel room."
He continued, "CHANSUNG and I used the room together. We both like to sleep without our clothes on, so were sleeping naked on that day as well."
He resumed, "Not long after we fell asleep, I heard someone using the key card to open our room. Then, I heard girls opening the door and entering our room. There were about five or six of them."

Ok Taec Yeon said, "They knew we were in there, and my heart started to race really fast. As they came near our beds, my eyes met theirs. They weren't Koreans, so I swore at them in English. They swore back at me."
He went on, "Thankfully, they weren't ghosts, but were sasaengs instead. I told the hotel staff about this, and they gave us a bottle of champagne to make up for their mistake."
He laughingly added, "We enjoyed the champagne. Thank you."
