After going public with their relationship this past July, Lee Min-woo of Shinhwa and model Go So-hyun have decided to call it quits.

Reps from both sides have confirmed the break-up, citing busy work schedules as the reason. According to reports, the two broke up this past fall.

Lee and Go were introduced through mutual friends and have allegedly been dating since the beginning of this year.

Lee is currently busy preparing for his year-end concerts while Go is hosting the show "The Body Show 2" on a cable network.
