2PM's resident hunk Taecyeon transcended his role as a labelmate and went full fanboy mode at the Wonder Girls' recent 'Wonder World' concert, openly cheering for the five ladies from the crowds throughout the night. Luckily for everybody else, his antics were caught on camera and posted on the internet for the world to see.

The 'Wonder World' concert opened with a performance by the JJ Project, and spanned over two hours. As the photo above reveals, Taecyeon had no qualms showing his support as he sat behind Girls' Generation members Tiffany & Seohyun, enthusiastically waving his arms and snapping photos throughout the concert.



Taecyeon wasn't the only star to attend the concert -- as previously reported, inactive Wonder Girls' member Sunmi, fellow 2PM members Nichkhun, Junho and Junsu, miss A, J.Y. Park, JOO, Leessang, Min Hyorin, Kang Mi Yeon, and more, were also in attendance at the 'Wonder World' concert. Talk about a star-studded event!
