5 Fast Facts About Katy Perry's New Video, 'Waking Up In Vegas'

The unstoppable, unsinkable, unflappable Katy Perry just released her latest video, "Waking Up In Vegas," which details the story of a wild, sleepless night in the city that really REALLY never sleeps.

So wake up, ante up, and find out five things very important things you need to know about Katy Perry's latest video.

1.) "Waking Up In Vegas" was directed by accomplished director Joseph Kahn, who's pretty much Britney Spears' go-to video guy. Joseph Kahn directed Britney's  "Womanizer" video, as well as "Stronger," and "Toxic." He directed Eminem's "Without Me" video, which won him a Grammy in 2002 as well as a 2002 VMA, and he directed Eminem's "We Made You" video.

2.) You're probably like "I know that guy in the video, but I don't know his name! Who IS that guy?" The guy in Katy Perry's "Waking Up In Vegas" video is an actor named Joel David Moore, and aside from roles on Six Feet Under, House, and Bones, Joel David Moore's also been in Dodgeball and will star in the upcoming movie, Avatar. He's also been in about a zillion commercials (basically, he's "that guy"), including that singing "Do It eBay" commercial.

3.) "Waking Up In Vegas" was filmed at The Palms Resort. Other videos filmed there include (ahem), Gym Class Heroes' "Clothes Off" video, as well as Eminem's "We Made You." Teairra Mari and Flo Rida just filmed "Cause A Scene" at the Palms, The Real World: Las Vegas was filmed there all the way back in 2002, and the Palms was also the location of the 2007 MTV Video Music Awards, which is where Britney Spears, well, you probably know how that went.

4.) The two guys Katy kicks out of her hotel room are Vegas magicians/ comedy staples Penn and Teller -- Penn's the tall one, and Teller's the one who rarely speaks. They also appeared in Run D.M.C.'s "It's Tricky" video back in the day. You've also probably heard Penn without realizing it -- he does lots of voiceover work for Comedy Central. There's also a poker pro in the video -- the guy Katy beats is real-life poker champ Daniel Negreanu.

5.) In the video, Katy wears real vintage costumes from Bob Mackie's personal collection. For the glam-oblivious, Bob Mackie is the esteemed fashion designer behind some of the most sequined, spangled, bejeweled, bedangled and outrageous costumes in the history of fashion. Remember the black feathered headdress Cher wore to the 1986 Oscars? That's Bob Mackie. (And if you still need them, check out more examples of glamourness -- ex-glam-ples?)
