Dang, talk about a creepy venue for a Halloween party!

The Madden brothers rocked Hollywood Cemetery Thursday night for the Vevo Presents Six Feet Deep Halloween Event Powered by DUBSET.

Paris Hilton dressed as Minnie Mouse for the event, while sis Nicky came dressed as her usual fabulous self, as did Jaime King (see her after the jump). Meanwhile, DWTS' Maksim Chmerkovskiy was surrounded by some hot girls whose costume we're pretty sure Nicole Richie would disapprove of ...



Benji and Joel performed a DJ set for the packed house ... guess they had cemetery residents rockin' 'n rollin' in their graves? ...

Dancing With The Stars pros Karina Smirnoff, Cheryl Burke and Maksim Chmerkovskiy are still in the running to win the coveted mirror ball trophy. But can their celebrity partners keep up the rigorous pace?

Good thing Maksim has calmed down since his outburst earlier in the week against lead judge Len Goodman. The exchange went as follows:

Goodman: "I've been in this business for 50 years."

Chmerkovskiy: "Then maybe it's time to go!"

Yikes ... pretty intense! These three professionals, showing off their casual side, have been dancing with the hit ABC dancing show since the beginning, and we have a feeling they'd love to take home the trophy! Plus, the extra money that goes along with a win must be a good incentive!

Justin Bieber is furthering his already-massive success with the new Christmas album Under the Mistletoe, and he's dishing on working with Mariah Carey!

On re-recording Mimi's "All I Want For Christmas" for the new album, Bieber tells Billboard:

"Yes, that was high. But I grinded it out and we got it down.”

The 17-year-old singing sensation added:

“I remember growing up not having a lot, especially around Christmastime. We had to get stuff from the food bank, so one of the charities we’re helping out is the food bank in my town. I want every one of my fans to feel like they’re helping out the world in some way. And being the one to influence them to do that, that’s something positive I can do with what God’s given me.”

Way to make Santa Claus proud, Biebs!

It seems the stress is getting to Demi Moore ...

Demi hid behind her hands as she left a West Hollywood nail salon Friday morning, shielding her super skinny body as she made her wait to a chauffeur-driven car.

Moore screamed obscenities, stunning on-lookers.

Our photographer tells us: "Demi was upset. I was just standing on the sidewalk, trying to get a few shots of her and she didn't want any part of it. She definitely wants OUT of the spotlight."

It appears the stress of infidelity accusations may be affecting Ashton too ... Wednesday night in New York (during a trip WITHOUT Demi), Kutcher addressed the crowd at the GQ Gentleman's Ball, dropping four-letter words and downing a few glasses of wine, according to reports.

Are these two headed for a breakup, a breakdown or both?

There's no time for rest when you're Kim Kardashian!

The 31-year-old reality star arrived at the Santa Monica airport bright and early to catch a private flight to New York. Too bad new hubby Kris Humphries isn't going along for the ride. Could this mean these two are too busy for each other?

In a recent X17 Poll, the majority of you voted that Kim and Kris' marriage was fake from the start ... and that they're headed for a split. Of course, Kim denies this is the case.

Even when taking a five-hour flight, Kim K still dresses to impress. Here she is on the runway sporting skintight jeans, a striped sweater, Channel bag and sky-high booties.

For this newlywed's fashion, the sky's the limit!

Seriously ... if you could be invited to any party, wouldn't you want to RSVP to Chanel?!

Well Kate Bosworth, Christina Hendricks and Elle Fanning were among the lucky few attending the chic boutique's evening soiree Thursday night. Bosworth brought along her hottie boyfriend Michael Polish to the exclusive dinner party.

Don't these ladies look lovely in their Chanel?! Wonder what's in that swag bag ...

Hottie alert!

Cameron Diaz looked super fine as she left Byron & Tracey salon Thursday.

The leggy star showed off her amazing bod in monochromatic gray jeans and matching blazer and booties.

And we love the blow-out with choppy bangs -- we just hope Cam doesn't cover up her new look! A recent report claims Diaz wraps her head with a scarf when she sleeps on flights so that she can protect her privacy. A source told the NY Daily News Diaz "feels vulnerable asleep in public, as a celebrity."

But we say, if you've got it, flaunt it!

Not sure how she does it, but Courteney Cox continues to defy the aging process!

The Cougar Town star, 47, enjoyed a wet and wild time while filming the ABC sitcom in Malibu. We'll admit, David Arquette's ex looks fab in that black wetsuit. Good thing she got to sit in the sand and relax in between takes.
