LOS ANGELES — We're in between filming here at the legendary Warner Bros. studio lot where tonight, America will decide who will take home the coveted title of "America's Best Dance Crew" — and here's what we've seen so far.

As we were filming some live hits, Beat Freaks, Team Millenia and Boxcuttahz all hit the stage together to rehearse their finale-opening performance, and were soon joined by Quest Crew, Dynamic Edition and Strikers All-stars. Then came the turn of Fly Khicks, Ringmasters and GOP.

In between, Mario Lopez was hard at work reading lines while talking on the phone at the same time — busy guy!

We caught up with JC Chasez backstage as he was getting ready to block the show and he's as curious as anyone about who tonight's winner will be.

The wardrobe department is working hard putting together several different outfits for almost 60 crew members, and there's even someone who goes around all the crews with a wet-wipe cleaning their shoes. (It's a tough job but someone's got to do it, I guess.) My personal award for best outfit has to go to the Fly Khicks — you'll understand why when you see the show tonight.

In between rehearsals, all nine crews kick it backstage like one big family, comparing moves, trying out new tricks and listening to music together. Even Dynamic Edition join in!

Out of curiosity, I took a look at the guest list. The award for biggest entourage for tonight is a tie between host Mario Lopez and judge JC Chasez, with Lil Mama following close behind — but with Mario actually on JC's personal guest list I think Mr. Chasez takes the award. It's a celebrity-packed audience as well, with Snoop Dogg, Lil Jon, some of the cast of "90210" and former "ABDC" winners SupaCrew all in attendance tonight.

Make sure you are too — the show airs tonight, live at 10 p.m. on MTV!

And even though the show may be over at 11 p.m., the party will continue as I host the live “America's Best Dance Crew” finale post-show, where we'll be talking to the winners, the runners-up, the judges and bringing you the real inside track from the "ABDC" finale!

The only thing missing behind the scenes at Britney Spears' Circus tour is a clown car. And who knows, maybe they've got one of those hidden around here somewhere ...

Minutes after Britney and her entourage arrived (at precisely 6:32 p.m. local time, btw) in a fleet of black SUVs, I was escorted through a labyrinth of corridors beneath the New Orleans Arena, past stagehands pushing platforms, dancers limbering up, crates of wardrobe, stressed-out makeup techs and stern-looking security guards to the nerve center of the entire operation: Britney's dressing room.

Of course, no photos were allowed, and I wasn't even here to talk to Britney ... I was there with the night's opening act, the Pussycat Dolls.

The Dolls were a bit tired -- after all, they had just flown in from Eastern Europe last night, and they were still working the kinks out of the evening's routine -- but I managed to ask them about the challenges of performing on an “in the round” stage, which gives the audience a 360-degree view of the action.

"The problem is, someone in the audience always has a view of your heiney," lead Doll Nicole Scherzinger explained.

Good to know. And while we'll have more on our chat with PCD tomorrow, I have to jet ... we're being led up to the press box right now. Looks like the Circus is about to begin!

It's the opening night of her Circus tour, and though doors don't open for roughly three hours, throngs of Brit's disciples — all decked out in their DayGlo finest — are already lining up for the big event.

Some have been here since 10 a.m., in fact — groups of fans from nearby towns like Lafayette and places like Jackson, Mississippi, each clutching homemade signs, singing Britney tunes, having impromptu dance-offs and letting anyone within earshot know that "it's Britney, bitch."

Justin, a 16-year-old from right here in New Orleans, wears a customized Britney jersey (his name is embroidered on the back) and swears he's her biggest fan. He's seen her on all of her tours (and had tickets for her Onyx Hotel show before it got canceled — he's not mad at Britney for that, btw) and is beyond pumped for tonight.

"It's going to be magic. This is Britney coming back," he enthuses. "I am so excited."

(It should be noted that though he swears he knows all Britney's dance moves, he refrained from doing any before the show. "I need to be energized," he said. "After the show.")

Nearby, in a line pressed dangerously close to a teetering security barricade, dueling Brit/ Pussycat Dolls fans Martin and Lauren — they're the ones from Lafayette — showed off their purple "Team Britney" and "Team Dolls" T-shirts and tried very hard to match Justin's intensity.

"This is my first ever show — period," Martin said. "This is the best way to lose my virginity! I cannot wait."

And neither could the others (trust me, they told me). T-minus three hours until the Circus begins.

Z100's Jingle Ball '08 is a wrap with easily one of the more talked about pop artists of 2008, Kanye West closing out the festivities. The press room was alive and chaotic today and some of the artists on the night’s roster were kind enough to make some time for us, as well as the plethora of young fans in waiting.

Although, Katy Perry, Leona Lewis (who judging by the camera crew surrounding her must have been shooting a reality show?), Rihanna, Chris Brown and Kanye West weren’t able to make it to the press area, former "American Idol"-er David Archuleta, Ne-Yo, Hayley and the gents from Paramore, Jesse McCartney, The Veronicas and the ever flamboyant Lady Gaga met up with us to share their year end news.

It was especially cool to observe the Veronicas meeting Paramore properly meeting for the first time (they waved hello to each other at the 2008 MTV Australia Awards).

First up was "Human," the new Killers single that the band performed a few weeks back on "Saturday Night Live." It features swirling synths and a galloping Pet Shop Boys-style rhythm, but what's really had people talking is that hook line: “Are we human, or are we dancer?" That's right: Not dancers, but dancer. Singular. The line, as the band's official Island Records bio points out, was inspired by a quote from Hunter S. Thompson, who once observed that America was "raising a generation of dancers." What exactly did the gonzo god mean by that, and how did it find its way into the song? "I just took it and ran with it," Flowers explained. "I think I know what he meant. I don't want to be too much of a preacher here, but you know, it's a mild social statement. And that's all I'm gonna say. We're just trying to write the best pop songs we can write." Fair enough. As for his lack of the plural on "dancer," he would only say, "I guess it bothers people that it's not grammatically correct. But I think that I'm allowed to do whatever I want."

I suppose so, BF. And I suppose, legally, that would include wearing whatever you want.

But that jacket Brandon's been sporting was definitely the other topic of conversation to come out of that "SNL" performance, particularly among my animal-loving friends, some of whom feel the singer should be redubbed "Brandon Feathers." He's always been a sharp-dressed dude, but this piece is something else — plumage sprouting from his shoulders like some avian admiral. Flowers jokingly tried to walk away when I told him I was a PETA member and seemed surprised to learn that the jacket was being discussed in the vegan community. He did, however, fill us in on who's responsible for it: British designer Fee Doran. "She goes by Mrs. Jones," he said, "and she's kind of an eccentric English woman who's worked with people like Kylie Minogue and the Scissor Sisters."

So, Fee Fi Fo Fum, is it owl? Is it pheasant? And is that, as some have suggested, fur on there too? "No fur," Feathers, er, Flowers said, adding, "I don't think anything was butchered for my jacket." Hm. Perhaps. There are fake feathers, but I have my doubts.

Are we human? Or are we butcher? We got no response, but perhaps you'd like to ask Mrs. Jones yourself. Good luck — and before you go thinking you might like to start sporting feathers yourself, I have one word for you: Icarus.

Which is why Fight Girls is a favorite Friday night past time in the Pak household. It’s a reality show about a house full of serious female Muay Thai fighters, who at the end of each episode are paired off in a winner-take-all, fight to the-death match!!! I’m not talking about the typical hair pulling, weave ripping, nail scratching girl fights. This is UFC style, professional ass kicking….RAD!!! So, this being Vegas, where any fantasy can come true, mine was to train with the Master himself, Master Toddy, the very man who teaches these girls to smack down. Vegas is a kick-boxing mecca, WHO KNEW???

What I lack in skill…it’s obvious, I make up in spazzy enthusiasm.

p.s. what's up with guys and their iphones? Are there any girls out there shelling out this money? Seriously.....I wanna know.....
