Taeyang of Big Bang will marry actress Min Hyo-rin early next year.
YG Entertainment, which represents the singer, confirmed that the two would wed around February next year before Taeyang's enlistment.
Taeyang is expected to join the military in the first half of next year.
The two confirmed they were dating in May 2015.
Min, 29, appeared in Taeyang's solo music video for "1AM" in June 2014. The music video, which includes passionate kiss scenes, is based on a storyline in which both Taeyang and Min yearn for each other after a breakup.
During a press event for his latest album "White Night" held in August, Taeyang professed his love for Min saying, "She is the person I love the most, and my biggest muse."
