Beliebers! Set your alarm because you need to be ready for "Bieber O'Clock."

"Bieber O'Clock" kicks off this Saturday, August 3 at 8 p.m. ET when MTV will begin airing exclusive content from Justin Bieber leading up to the television premiere of his 2011 film, "Justin Bieber: Never Say Never," which airs Sunday at 8 p.m.

"So for the next 24 hours, you guys are going to get some exclusive interviews of me and my friends and my crew and maybe some people that don't even know me," Bieber said in a teaser clip. "We know there's a lot of stuff out there that people just don't know."

And fans better keep their eyes locked to the screen because Bieber is getting personal and addressing some of those rampant rumors.

"Do I have a monkey? Do I not have a monkey? Do I spit off balconies? Do I not spit off balconies? Do I choose to wear my shirt in inappropriate places? Do I not choose to wear my shirt in inappropriate places? I don't know, but you might know," Bieber said. "The next 24 hours you might find out why I really do not like wearing shirts." "Bieber O'Clock" will include some of the "Girlfriend" singer's favorite MTV moments, including exclusive interviews from Bieber's "Never Say Never" co-stars — manager Scooter Braun, mom Pattie Mallette and best friend Ryan Butler.

Being that this is a Bieber event, he wanted to get his Beliebers involved. Not only will fan-submitted videos be featured throughout the day, but viewers can stay tuned for a special contest. A hashtag will be revealed, and fans can tweet it for a chance to win a DVD copy of "Never Say Never," signed by the cast including, of course, Justin himself.

Set your alarms for "Bieber O'Clock"! Starting Saturday at 8 p.m. ET, look out for a special Bieber moment every hour for 24 hours leading up to the premiere of "Justin Bieber: Never Say Never" on Sunday at 8 p.m. ET.
