How should I approach/talk to a random girl in class who's never alone?

There's this cute girl in one of my lectures that I wanna talk to. She seems like a typical nice, asian girl. The thing is, she's always with a friend which means she's never alone. To make matters even more complicated, she talks to her friend in another language during class too. I know she speaks English though but I have no idea what her name is and I don't like anonymous adds on Facebook anyways. How should I go about this?
