On August 18, their management agency YG Entertainment announced, "Lee Sung-kyung and Nam Joo-hyuk have decided to go separate ways. We cannot tell you the reason behind their break-up as it is their own privacy."
The pair admitted to be in a relationship in last April, but they have decided to break-up after four months of dating.
Meanwhile, Lee Sung-kyung is preparing for her upcoming film 'Love Sling' and Nam Joo-hyuk is playing a role at tvN's drama 'The Bride of Habaek'.
