2PM member Junho's 'washboard' abs have been revealed.

On June 20th, Junho shared the photo above on his Twitter page and wrote, "Sharing a photo, as we haven't been promoting. A photo that was slightly revealed during the concert.. goodnight everyone."

The photo of Junho at what appears to be the gym immediately caught the attention of netizens everywhere, as they revealed his defined 'washboard' abs.

2AM's Seulong who also saw the photo wrote, "So can I leave my laundry with you?", to which a confused Junho replied, "What are you talking about?"

Seulong then expressed his frustrations writing, "Have you never even heard of washboard abs? Can't believe this. Doesn't even make sense. Daebak," causing his fans to burst out into laughter.

Junho's Twitter followers who saw the photo remarked, "I had no idea he was so ripped", "I really could do my laundry on those abs", "Flawless body", and more.
