The girl band 2NE1 may be huge in South Korea, but that's not enough for the the four-piece.
They're now trying their luck in America, as CL, Minzy, Dara and Bom begin performances in the States.
The ladies have also been working with will.i.am, and though they admit they were nervous to start with, they soon became good friends.
Minzy said: "My impression was that music was at the base of his life, he lives his life through music. And he almost felt like a friend and we ate Korean food like chicken porridge soup together."
