f(x) to make a comeback with "Rum Pum Pum Pum" + new group and individual teaser photos

Their upcoming title track, which has been given the name "Rum Pum Pum Pum" for its English title ("First Wisdom Tooth" is the actual Korean title), is a pop dance track that compares belatedly finding one's first love to a wisdom tooth that grows last as it pushes aside the other teeth.

You don't have to pinch yourself to make sure that this is all happening as their comeback stage dates are also set! They'll actually be kicking off their comeback stages prior to the album release, starting off with their performance at 'M! Countdown' on the 25th. The 2nd full-length album 'Pink Tape' will be released on and offline on the 29th!

Individual pics have also been released, so check them out below.
