It seems that fans waiting for f(x)'s comeback do not have to wait much longer!

On September 11, a representative of SM Entertainment officially confirmed with My Daily that the girls are hard at work filming their newest music video. The members of the group travelled to Jeju Island on the morning of September 11 to film in secret privacy.

Not much about their latest comeback has been revealed to the public thus far. Member Krystal is even reported to have worn wigs and beanies to hide her hairstyle through the summer.

Since f(x) is known for surprising fans with a variety a music smiles and transformative appearances with every comeback, they especially want to keep everything about their next comeback an absolute surprise for their fans. The excitement for f(x)'s return undoubtedly runs high amongst their fans.

This is also the group's first album after becoming a four-member group when Sulli formerly departed to focus on her acting career.

Many fans are curious how f(x)'s sound will change without Sulli's inclusion.

f(x)'s last comeback "Red Light" was released about a year and three months ago.

However, due to a variety of factors their promotions for "Red Light" only lasted three weeks. Since then the members have pursued many different solo activities. Now that the group will be back soon, anticipation only rises!

The new title track and album is scheduled for release in early October.
