After School's Jooyeon and actor Lee Tae Sung recently partnered up for MBC Music's 'Music and Lyrics 2' and collaborated together to produce a CM song.

It has been revealed that Jooyeon and Lee Tae Sung spent numerous nights on top of their busy schedules to co-write this song, and a portion of it will be unveiled on the episode scheduled to air on the 29th at 11PM KST.

This upcoming episode will also feature Jooyeon and fellow member Lizzy successfully pulling off a hidden camera prank on Lee Tae Sung by pretending to have a fight, which ended up making Lee Tae Sung nervous. To support each other, the co-stars also prepared homemade meals for each other and went on a romantic drive date.
