Most sisters can't even get through a family road trip without dividing the backseat in half and not allowing the other to cross the imaginary line. But Catherine and Allison Pierce are way beyond that. Sure, the Alabama-born, New York-based sisters have their sibling issues, but they put their shared genes to good use in making their own brand of sassy, yet whimsical folk-rock. We got to chat with Allison (the blonde) about celeb gossip, exacting revenge on an ex, and of course, their stint on Gossip Girl!

What was it like on set?
It was fun! Everyone was really nice. We shared a dressing room with Blake and Leighton, and they were very sweet girls -- fun, seemed pretty laid back. Giggled, laughed a lot. Met some of the boys -- very cute, even cuter in person. It was interesting to watch them act. You don't see people acting [very often] and it being filmed, or I don't. You see it on TV, [but] it's so different when you see it in person.
