It was only a short time ago that 2PM singer and actor Nichkhun and Girls Generation member Tiffany filmed cameo performances for the popular drama "Producer." Now the real-life couple has broken up and both are focusing on June comebacks with their respective groups.

Their agencies, JYP Entertainment and SM Entertainment confirmed the break-up news.

"It is true that the two recently broke up," said a JYP Entertainment representative.

"After checking with Tiffany, it has been confirmed that they broke up," said the SM Entertainment representative.

As to the reason for their break-up, neither agency offered more information. But it's no secret that demanding schedules keep celebrity couples apart and the lack of time together can contribute to the break-up of star relationships.

"The reason they broke up is a personal matter, so there was no mention of it," said the JYP representative. "Nichkhun is currently in the middle of preparations for 2PM's comeback."

The singers began dating in January 2014 and went public with their relationship in April 2014. According to their agencies, they have parted as friends.

Nichkhun appears in two films this year, a Thai film "Chalouis," and a Chinese film "Gardenia in Blossom."
