20 Behind-the-Scenes Secrets from Gossip Girl
Leighton Meester First Auditioned for Serena
How different would Gossip Girl have been if Leighton Meester had played the other lead role? That was almost the case, as Leighton originally auditioned for the role of Serena. In an interesting twist, it was Leighton herself who told the producers that she felt she was a better fit for Blair.
Her intuition on that front undoubtedly paid off. Leighton probably wouldn’t have made a great Serena, and Blake Lively was a perfect fit for that role. Conversely, she was an outstanding fit for the role of Blair and played her to perfection over the course of six seasons.
