Block B member U-Kwon expressed his annoyance at a hacker after his Instagram was hacked and a break-up rumor with his girlfriend was posted on Sunday.

U-Kwon said via Instagram, “I have no idea who did this but don’t do it again. The post is fake and I’ll take proper measures if this happens again.”

The reason behind this stern warning appears to be a netizen’s repeated hacking. The netizen, who impersonated U-Kwon, had posted that the singer broke up with his model girlfriend Jun Sun-hye. In response, the 23-year-old clarified himself to stop spreading the false rumor.

Earlier in 2012, U-Kwon revealed his relationship with model Jun Sun-hye. This attracted the public attention as it is an exceptional manner for an idol to admit to dating.
