2PM’s Junsu is featured in T-ara’s Bo Peep Bo Peep?

T-ara's performance of Bo Peep Bo Peep on Music Core earlier today had a special male voice in the background. People were confused as to who it was and whether or not it was a mistake.

It was none other than 2PM's Junsu! And was later confirmed by Taecyeon and 2AM Seulong's posts on Junsu's mini-hompy.

Taecyeon wrote, "You singing Bo Peep Bo Peep was aired. Go apologize to T-ara right now!" Seulong wrote, "I knew it was Junsu as soon as I heard it."

Netizens commented, "His voice. Jun Peep Jun Peep," and "Junsu's featuring. So funny!"

Isn't this whole accident pretty hilarious? Of course it's 2PM who caused this
