K-pop boy band 2PM members Taecyeon and Chansung have spilled the beans on a time when hardcore fans surprised them while they were sleeping in the buff in a hotel room in Singapore.

On the latest episode of variety show Ask Us Anything, Taecyeon, 32, recounted the incident: "When we went to Singapore for a concert, we stayed in a hotel, and Chansung and I shared a room. But the thing is, Chansung and I don't wear any clothing when we sleep."
