Tyra Banks, Hilary Duff, Karlie Kloss, Lady Gaga, And More Were All Guest Stars On 'Gossip Girl'

ICYMI, Gossip Girl was pretty much one of the most iconic shows of the last decade. Come on: The drama, the gorg cast, the ~fashun~, and the New York City backdrop made for amazing television. I could literally watch their crazy-AF lives unfold for hours (and I have) and *never* get bored. In fact, sad as its sounds, I think I was inspired to move to New York just because of my GG obsession. (We can unpack that later, lol.)

That said, if you haven't watched the show in a while (can't relate), then you actually might've forgotten that some now-suuuper famous celebs actually guessed starred on the show, either before they became well known or as cameos because, duh, they're kiiind of a big deal (*cough cough* Vera Wang). Picture this: Hilary Duff, Lady Gaga, Liz Hurley, Kristen Bell, and more *all* made appearances on the show at some point or another.
