It has been announced that singer Kim Sung Soo (42) of the old school k-pop trio COOL will be divorcing his wife of 6 years. If you're an old school k-pop fan, you'll definitely remember COOL. They started their journey back in 1993 and then broke up in 2005 - only to get back together 3 years later. Since they've reunited, however, they've released two albums that have yet to bring back the heat they once had. Kim Sung Soo's aide reported, "On the 13th, Kim Sung Soo and his wife Ms. Kang Mo both visited Seoul and went to the Seochongdo Seoul court and applied for a divorce." When asked why the couple were splitting up, the only answer was that it was due to "character differences". The couple wedded in February of 2004.
