Before "The Twilight Saga's Breaking Dawn Part I" opens in theaters across the U.S., an official fan convention for the vampire series will be held in Los Angeles in early November. An announcement on the event's official site revealed that Robert Pattinson, Kristen Stewart and Taylor Lautner are set to appear as the special guests, and an exclusive footage will be screened.

The "Twilight" trio are scheduled to be on hand at a "Welcome to The Twilight Saga" panel that will take place at Hyatt Regency Century Plaza Hotel in Century City on Saturday, November 5. On the same day, the likes of Peter Facinelli, Elizabeth Reaser, Jackson Rathbone, Ashley Greene, Nikki Reed, Tinsel Korey, Charlie Bewley and Alex Meraz will also make special appearances.

A day prior, on November 4, other "Twilight" stars like Julia Jones, BooBoo Stewart and Mia Maestro will appear at the convention for an autograph and question & answer session. Additionally, there will be a "Twilight Saga Wedding Reception" party where Twihards can enjoy a party with fellow fans around the world on the final day of the convention on November 6.

In the meantime, a brand new clip from "Breaking Dawn I" has landed online. While a previous clip shows the moment when Bella and Edward arrived at their honeymoon suite, this new snippet sees Bella preparing herself in the bathroom for her first night with her new husband, Edward.

Directed by Bill Condon, "The Twilight Saga's Breaking Dawn Part I" is due to arrive in theaters across the United States on November 18 this year. Its follow-up, "The Twilight Saga's Breaking Dawn Part II", is slated for November 16, 2012 release.
