Kim Jaejoong, a member of male idol group JYJ, will be enlisting in the Korean army at the end of March, announced JYJ's entertainment agency, C-JeS Entertainment.

Kim joins the lineup of several popular Korean idols, who will be enlisting in the Korean army in March to fulfill their mandatory military service. Kim will reportedly enlist on the same day as Super Junior member Sungmin.

A C-Jes Entertainment representative confirmed the news to Korean outlet Newsen on March 4.

"JYJ's Kim Jaejoong is confirmed to enlist in the army on March 31," the rep said.
