What You Didn't Know About The New Hosts Of "Punk'd"

You can bet the new season of "Punk'd" will feature some pretty intense pranks, but adding to the excitement is the way each episode will be hosted by a different celebrity. Check out some little-known facts about the new group of pranksters, and be sure to watch the show every Thursday at 10/9c, on MTV.

There's very little we don't know about Justin Bieber. But only his most devoted fans know his shoe size is 7 and a half, and that he's claustrophobic. So if he's afraid of tight spaces, does it mean he's found a pleasant way to travel around the country that he's not sharing with the rest of us?

Few people know Miley Cyrus is a vegetarian, but doesn't eat anything green. Hasn't she heard about what happened to Paula Deen?

Bam Margera's real name is Brandon Cole Margera, but he earned the nickname "Bam" from his grandfather because he kept crashing into walls as a kid. He's known for appearing on "Jackass," but Bam has also written, produced, and starred in three independent movies.

Hayden Panettiere

Hayden got her start in commercials, and filmed her first ad for Playskool when she was just 11 months old. She'd probably rather talk about her experience in the entertainment industry than she would of her tattoo that reads, "Vivere senza rimipianti" (which would mean "to live without regrets" in Italian if "rimipianti" was spelled correctly).

Dax is the guy who delightfully got Kristen Bell a sloth for her birthday! But when he's not recording his fiancée's overreactions he's volunteering at the Hollenbeck Youth Center, which provides opportunity to at-risk and inner-city youth in Los Angeles and being friends with Tom Arnold.

Heather Morris got a leg-up in her career from Beyoncé, when B made Morris one of her backup dancers from 2007 to 2008. And that's how "Glee's" Ryan Murphy found the future Brittany S. Pierce: he hired her to teach the cast the "Single Ladies" dance. Now if only she was available to teach the rest of us.

Before Kellan was involved with the "Twilight" movies, he starred in Hilary Duff's music video for her song, "With Love," and appeared in the commercial for her perfume. Kellan also considers himself to be "old-school" because he believes in abstinence (even though his smirk definitely doesn't).

Lucy Hale

Lucy appeared on Ryan Seacrest's singing competition for kids, "American Juniors," in 2003. She went on to have minor roles on NBC's "Bionic Woman," "The O.C." and "How I Met Your Mother." But what is most revealing about Lucy's personality is that she loves watching the professional organizers uncover dead cats on A&E's "Hoarders."
