Just a few weeks before "The Twilight Saga: Eclipse" hits theaters, its stars are going to create havoc in Century City, Calif.

Robert Pattinson, Kristen Stewart and Taylor Lautner will attend a "very special panel" on Saturday, June 12 at the official "Twilight" convention held from June 11-13 at the Hyatt Regency Century Plaza.

Fans better soak up all they can, however, because according to the convention's website, the trio "will not be available for autographing or photo ops."

True Twihards will still have plenty of opportunities to hobnob with other "Twilight" stars though on the following days:

Friday, June 11: Justin Chon (plays Eric Yorkie), Tinsel Korey (Emily), Michael Welch (Mike Newton), Kiowa Gordon (Embry Call)
Saturday, June 12: Gil Birmingham (plays Billy Black), Tyson Houseman (Quil Ateara), Daniel Cudmore (Felix), Christian Serratos (Angela)
Sunday, June 13: Justine Wachsberger (Gianna), Cameron Bright (Alec), Christopher Heyerdahl (Marcus)

BooBoo Stewart, who plays Seth Clearwater, will be available all three days.

Among the fun activities are a musical karaoke concert featuring Michael Welch on Friday and two scheduled Volturi Vampire Balls.

"Eclipse" is in theaters beginning June 30.
