Meanwhile, Pattinson's former girlfriend Kristen Stewart will make her first appearance post-split at the Toronto Film Festival to promote her next film "On The Road" on the same date and time.

It will be Stewart's first public appearance since the cheating scandal that involved her affair with "Snow White and the Huntsman" director Rupert Sanders. Attendees at the red carpet premiere at the film festival are not sure what to expect.

In the October 2012 issue of British Vogue, Stewart discussed her discomfort with fame and being in the public eye.

"If I were to sit down and think, 'OK, I'm really famous, how am I going to conduct myself in public?' I wouldn't know who that person would be! It would be a lot easier if I could, but I can't know if you haven't thought about how you want to present a very packaged idea of yourself then it can seem like you lack ambition," she said.

Tonight's debut of the final trailer is considered the most important Twilight event until the film's release to a "Twi-hard" fan.

"The Twilight Saga: Breaking Dawn - Part 2," starring Robert Pattinson, Kristen Stewart and Taylor Lautner arrives in theaters Nov. 16.

Check out the final trailer when it premieres at the VMAs Thursday (September 6) at 8 p.m. ET to find out.
