Some of the stars of the upcoming "Twilight Saga: Breaking Dawn - Part 1" will be hitting the road next month for a barnstorming tour to jack Twilighters up even more about the penultimate film in the vamps-and-werewolves saga.

Peter Facinelli, Jackson Rathbone, Nikki Reed, Kellan Lutz and Elizabeth Reaser will pile into the van (OK, probably a plane) for a five-city tour from November 7 to 11 that will hit Atlanta, Chicago, Dallas, San Francisco and Salt Lake City, just one week before the movie hits screens (November 18). They will be joined by singer and "Breaking Dawn" soundtrack contributor Christina Perri on the first three dates. Three other soundtrack contributors — Aqualung, Lucy Schwartz and Sleeping at Last — will be on hand for the final two shows.

Tickets for the appearances are free and will be available beginning at 10 a.m. local time Saturday, November 5, at each location, with a two-ticket-per-person limit. Each event will feature a red-carpet arrival followed by the mini-concert.

If you just can't wait that long, tune in to MTV at 7:54 p.m. ET on Wednesday, October 26, to see the debut of the video for the first single from the "Breaking Dawn - Part 1" soundtrack, "It Will Rain," from Bruno Mars.

The "Rain" video will feature a never-before-seen clip from the film. Immediately following the video's premiere, the action switches over to MTV.com for a live stream featuring MTV News correspondent Sway Calloway's exclusive interview with Mars, plus "Twilight" music supervisor Alexandra Patsavas, who will discuss everything about the "Breaking Dawn" soundtrack.

"After seeing the movie, I thought that it would be a perfect fit," Mars told Billboard last month about the lead single from the soundtrack. "The 'Twilight' movies for me [are] a love story. But it's a dark love story," he added. "And I think the best way to describe the song is: It's the darker side of love. I think that pretty much sums it up."

Mars will also be answering your video and text questions, which you can submit starting today at MTV.com or via Twitter using the hashtag #AskBruno.

» 11/7 - Atlanta, GA @ The Buckhead Theatre (Greene, Reed, Facinelli, Rathbone and Perri)
» 11/8 - Chicago, IL @ House of Blues (Greene, Reed, Facinelli, Rathbone, Lutz, Reaser and Perri)
