Who is Gossip Girl? For five years, that's been the secret she'll never tell.
This fall, however, the show's biggest mystery will finally be revealed!
In a new promo teasing the final season, which gets underway Monday night, executive producers Stephanie Savage and Sara Goodman promise that by the end of the 10-episode farewell, we will have our answer.
The cast members themselves are asked for their theories, which include:
- Blake Lively's dog Penny
- Vogue editor Anna Wintour
Pretty fun promo, and pretty cool that they're going to answer the question at all. Who do YOU think Gossip Girl is? Someone we know or a character we haven't seen before? Share your guesses below!
