Wonder Girls are currently enjoying the limelight and love of their fans as their second album and title track Be My Baby have been a hit with many. And now, their labelmates, 2PM and 2AM have joined in on all the fun, not wanting to miss a single beat.

Specifically, Wooyoung, Taecyeon, Junho, and Chansung, as well as Jo Kwon, took much delight in joining the girls while they were practicing. Wooyoung is first nodding his head to the beat before taking part for the dance when it came time for Yubin to rap. Junho and Chansung also provided for much amusement (and distraction) when Ye Eun went solo.

During the pre-recording of Inkigayo, Taecyeon and Jo Kwon joined in the fun, much to the screaming delight of fangirls present.
