Remember how f(x) was supposed to open for world star Beyonce? It never happened! f(x) was nowhere to be seen at Beyonce's Seoul concert. Fans were very confused at not seeing the quintet on stage before the diva came on. SM Entertainment stated on the 21st that f(x)'s performance got canceled 2 hours before the concert. Because of f(x)'s absence, Beyonce had no opening act. SM Entertainment continued to say, "Around 6:00PM, we heard that they canceled the opening act. We wanted to get them on stage somehow but it couldn't happen and we are disappointed about it." After f(x) was all dolled up and done practicing to get on stage for Beyonce, the concert's planning representative from B4H Entertainment informed the girl group that they can not perform as the opening act which left them speechless and confused. There was supposedly a miscommunication between Beyonce's representatives and B4H Entertainment. B4H Entertainment didn't make it clear to Beyonce's representatives that f(x) were to open for her. There was no other solution but to drop f(x) out of the concert. SM Entertainment didn't even get to know the reason why. Though Beyonce still had a successful concert, I bet f(x) was surely disappointed they had to pass up the chance to share a stage with Beyonce.
