Fans have been wondering just what is going on with f(x) and their activities as the group seemed to have suddenly stopped promoting and their upcoming schedules have been wiped clean. SM Entertainment has finally addressed the issue to announce that Sulli has expressed her wish to take a temporary hiatus from her activities.

The agency revealed through the group's homepage,

Hello.

It's S.M.ENTERTAINMENT.

As we say thank you to the fans who love f(x), we have an announcement to make. [f(x)] member Sulli became mentally and physically exhausted from the continuous, malicious comments and false rumors, and has expressed her wish to take a break from her celebrity activities for the time being. 

After careful deliberation and taking her wish into consideration, we will reduce her activities and let her take a break for the time being. 

Also, f(x)'s promotions for their 3rd full-length album 'Red Light' ended with their stage on SBS' 'Inkigayo' last week. f(x) will continue on activities with the SMTOWN Seoul concert on August 15 and overseas promotions, as well as individual schedules for the remaining four members Victoria, Amber, Luna, and Krystal. 

We regret to inform fans of this news and we ask that you continue to show your support and love for f(x). 
Thank you.
