A music industry insider told SportsToday, "Girls' Generation's Taeyeon and EXO's Baekhyun have recently ended their relationship. Taeyeon and Baekhyun both focused on their individual activities and naturally grew apart."
They added, "Even last March, Taeyeon secretly attended EXO's solo concert in Seoul and displayed her affection for Baekhyun, but they eventually weren't able to overcome their busy schedules. Although the two have ended their romantic relationship, they have decided to remain good sunbae and hoobae."
Taeyeon and Baekhyun admitted they were in a relationship back in June 2014, and were the first revealed couple both from SM Entertainment.
The agency says they're looking into the situation to confirm the news, so be on the lookout for any possible updates to come.
