The worst-kept secret in Hollywood is finally a reality. Sony Pictures announced today that Emma Stone will play Peter Parker’s love interest in Spider-Man. The surprise: she’ll be playing Gwen Stacy, not Mary Jane Watson as we had heard. The film will be directed by Marc Webb (500 Days of Summer) and stars Andrew Garfield — who can now be seen in The Social Network — as Peter Parker.

Sony and Stone go way back. Stone has starred in Superbad, The House Bunny, Zombieland,and the recent Easy A for the studio. To say she is one of head honcho Amy Pascal’s favorites would be an understatement. Says director Webb, “The chemistry between Andrew and Emma was stunning and made Emma the clear choice.”

Looks like Emma will be going back to her natural blonde roots for the role of Gwen.
