Justin Bieber In 3-D Is ‘Insane,’ Jimmy Fallon Says

'Never Say Never' star is up for Best Jaw Dropping Moment at Sunday's MTV Movie Awards.

Justin Bieber is known for making his fans scream their heads off whenever he’s around, so it’s no surprise that he’s up for Best Jaw Dropping Moment at the 2011 MTV Movie Awards for his 3-D concert spectacular “Never Say Never.”

When MTV News caught up with two-time MTV Movie Awards host Jimmy Fallon on the Universal Studios lot, just a stone’s throw from the Gibson Amphitheatre where Sunday’s show will take place, he explained Bieber’s jaw-dropping abilities.

“Bieber is just so jaw-dropping because Bieber in 2-D is enough, [but] Bieber in 3-D? Hold on to your horses,” he said of the pop superstar, who is up against James Franco (“127 Hours”), Leonardo DiCaprio and Ellen Page (“Inception”), Natalie Portman (“Black Swan”) and Steve-O (“Jackass 3D”). “It’s insane.”

Fallon, the new host of Universal Studios Hollywood’s behind-the-scenes Studio Tour, knows a thing or two about the Movie Awards, since he co-hosted with Kirsten Dunst in 2001 and returned solo in 2005. He’s pretty sure fellow “Saturday Night Live” funnyman Jason Sudeikis, who is tapped to host the show this year, has it in the bag when it comes to hosting.

“It’s exciting. The Movie Awards are the most fun. Jason Sudeikis is a great host; he’s going to be great at it,” he said. “I’ve hosted in the past. I hosted with Kirsten Dunst. It’s just a blast. MTV just brings the fun back into movies.”

Sudeikis may already know what he’s doing, but he did add some words of encouragement for his buddy: “Jason, you know what to do, buddy. Kick some butt over there.”
