What's better than a front-row seat at a Justin Bieber concert? How about exclusive access to the red-carpet premiere of the Biebs' "Believe" documentary?

MTV is taking you there with the best seat in the house as Bieber, director Jon M. Chu, producer Scooter Braun, Usher and more answer your big questions during our online live stream, kicking off at 9 p.m. ET/6 p.m. PT exclusively on MTV.com. Have a question?

MTV News' Christina Garibaldi will be joined by guest co-host Debby Ryan, of Disney's "Jessie," for all the action. And if we know Justin's fans, it's going to be pandemonium.

"Last time, when we did 'Never Say Never,' there was like, 4,000 fans outside screaming, going crazy," Chu previously told MTV News. " I'm sure there's gonna be some wild fan costumes and signs."

Lest we forget about graffiti artist Alec Monopoly, who will be creating an installation for the event using Bieber's Music Journals singles cover art as inspiration and infusing his own energy and emotions. The work will be painted live on-site and auctioned off for charity upon its completion.

Need more reasons to tune in? Chu will give you five.

"Believe" is what the director calls a "transition movie," giving audiences an inside look at Bieber's life as he records, tours and attempts to evolve under intense media scrutiny. "This was about him transforming and growing," Chu told MTV News.

"Believe," a follow-up to 2011's "Never Say Never," hits theaters on Christmas Day.
