Bounty Hunter star Lee Min Ho and K-pop singer/actress Bae Suzy have allegedly broken up after 15 months of dating.

According to CSN, Suzy is reportedly seeing someone from her past and could possibly be rekindling an old fling. Suzy and her former lover had been spotted on a number of dates before photos of the singer and Lee on a date in Paris and London started making rounds on the Internet, according to Fashion & Style.

According to Yibada, Suzy used to have a crush on another man but ended up with the Boys Over Flowers actor. Now, fans are speculating that if Lee and Suzy call it quits, it would be because of Suzy's affair with another man.

This is not the first time the couple has had to deal with break-up rumors. Last year, JYP Entertainment, Suzy's agency, clarified that the couple's relationship is going stronger than ever amid speculations that they were on the verge of splitting.

"After asking Suzy, we have learned that the breakup reports are false. They are meeting well," an insider from the JYP Entertainment said. "It's not true that they broke up."

Lee and Suzy's romance was officially confirmed in March last year, after the two openly acknowledged their relationship by posting photos of their dates in London in March 2015.

Meanwhile, the couple is yet to confirm the latest rumors about their break-up. So far, both have kept mum about the issue as they are busy with their respective ongoing projects.

On the other hand, Lee's upcoming movie Bounty Hunters is set to hit Chinese theatres next month. The action/romance film revolves around a group of bounty hunters who are chasing fugitives across China, Korea, Thailand, and Hong Kong.
