If you’re not yet familiar with K-pop act Girls’ Generation, think Britney Spears at the height of her popularity plus Spice Girls. That’s how big they are everywhere in the world, except for maybe the United States, which is the last to arrive at the party. But even in the U.S. the Korean girl group is quickly gaining fame. Last year, the nine-member-strong group won the inaugural YouTube Music Awards’ Video for “I Got a Boy.”

That was just the beginning of Girls’ Generation’s global takeover. This past August, the girls triumphantly headlined the closing night of KCon2014, performing for tens of thousands of shrieking fans at Los Angeles’ Memorial Sports Arena. Right before they took stage, Fusion caught up with members Tiffany and Seohyun to chat with them about their current album, “The Best,” their latest comeback, and why their fan base is the best. Check out the video to see what they had to say.
