Girls' Generation's YoonA, f(x)'s Sulli, and EXO came together for another round of CFs for 'SKT LTE'!

YoonA and Sulli get goofy by singing and dancing along to the 'SKT LTE' jingle while EXO watch in fascination like adorable fan boys. EXO also have a dance party of their own as they hilariously shake their phones.

Check out the dance party in the CFs below!
