SEOUL (KOREA HERALD/ASIA NEWS NETWORK) - K-pop singer Taeyang from wildly successful boy group BigBang is in a relationship with actress Min Hyo Rin, both their agencies confirmed on Tuesday.

Taeyang, 27, is believed to have started dating Min, 29, in 2013.

He is signed on to talent agency YG Entertainment, while Min is signed on to JYP Entertainment - two of the most powerful record labels in K-pop.

"Their relationship is already a well-known fact among K-pop idol singers," an unnamed friend of both stars told Yonhap News Agency on Tuesday.

"They are in quite a serious relationship," said another singer, who is close to Taeyang and declined to be named. "As far as I know, they've been together for the past two years. They suit each other in terms of their personality and appearance."

Min appeared in Taeyang's solo music video for 1am last June. The music video, which includes passionate kiss scenes and bed scenes, has a storyline where Taeyang and Min yearn for each other after a break-up.

Min, who has an innocent image, started her career as a television commercial model in 2006. She transitioned to acting and appeared in the films Sunny (2011), The Grand Heist (2012), A Millionnaire On The Run (2012) and Twenty (2015).

Taeyang has publicly stated that he was born to be single, though he has fallen in love unrequitedly.

Suspicions of a relationship surfaced when the two were spotted in public wearing matching "couple" sneakers and pants.

However, when questioned about Taeyang's relationship status, his agency YG had always refused to comment.

Min's agency JYP, in contrast, has always been frank about its artists' relationship status, which may explain why YG had to follow suit chose to follow suit with regard to Taeyang's current relationship.

BigBang are currently promoting their album Made, and released a second installment, A, on Monday.
