Even when he's in a mismatched suit and showing off a set of false teeth, we still find David Arquette charming and irresistible!

The Scream funnyman was spotted arriving at a private party in Beverly Hills on Friday night, and he tweeted, "Happy Halloween! I had all these clothes in my house. I may have been a pimp in a past life." Ha! Wonder if he was able to find any ladies to play his hos for the night?

We also spotted Petra Ecclestone dressed as Jessica Rabbit, and we're not sure what her hubby James Stunt dressed as, but at least he was warm!

Yesterday Justin Bieber arrived on set for his Proactiv commercial in Los Angeles, and the 17-year-old pop star sported a wide variety of different outfits throughout the day, along with a drastically different new hairstyle. While we miss his long bangs, we have to admit, he definitely knows how to rock a spiked up 'do! Maybe because it makes him look a little bit taller older?

Justin recently posted a clip of Johnny Depp's hilarious interview with David Letterman earlier this week to his Twitter account. Johnny discussed his experience meeting the young pop star, and Justin wrote, "Im a big fan of Johnny Depp. the guy can SUMMON me. haha." Aww!



What do you think of Justin's new 'do?

Justin Timberlake may be back together with Jessica Biel, but the 30-year-old actor/singer recently admitted that he has the hots of a member of the royal family!

"Us American males are big fans of Pippa [Middleton]," Timberlake told Esquire UK's latest issue. "We like the Middletons very much. I'm going to sound like a sleazeball. I'm going to stop right there!"

While Pippa may be flattered by JT's comments, she recently reunited with beau Alex Loudon, so we highly doubt a hookup between these two would ever happen, but who knows?! This is the guy who once dated Britney Spears...

Last night Paris and Nicky Hilton headed to a Halloween bash in Hollywood, and the sisters were all dolled up and ready to party when we snapped their picture. Nicky dressed as a sexy cat (we know how much she loves her own kitties!) and Paris made everyone's jaws drop with her outfit.

Before heading out, Paris tweeted, "Bought so many cute costumes. Can't decide which to wear. Super Woman, Shera, Snow White, Tinkerbell, Goldie Locks or a ballerina. Thoughts?" Apparently the decision wasn't that hard for Miss P, because after that she wrote, "Thanks for your suggestions. I've made tonight's costume decision ... I'm bringing back old school and being Shera! In case you don't know, she was that super hero from the 80's who dated He-Man. #YES!"

Do RPatz's funny faces translate, we wonder?

Swedish Twilight fans got a peek at Robert Pattinson's goofy side today at a convention in Stockholm.

And the actor was unusually candid about his years-long relationship with Twilight co-star Kristen Stewart. Pattinson admitted the two may even be married!:

"The wedding scene's funny because we used a real priest. So technically we are already married because he did all the things you would do in a normal ceremony. So we don't have a civil union in law, but I guess in the church we are actually married."

Rob went on to describe the intimate sex scenes his character has with Bella [Stewart] in the upcoming fourth installment of the hit film series, Breaking Dawn:

"It was very charged, but a very tender and sentimental scene. It's not a scene from the book, so everyone was nervous about doing it right," he explained. "A ton of other people were nervous. And, Kristen and I were both worried about the shape of our bodies would look on camera. We felt vulnerable."

In the film, it's Stewart's character that initiates intimacy with Pattinson's Edward character. Rob commented at today's press conference that he likes the twist, but wonders what the moral of it is:

"I've never been able to relate to that fear of sex or sexuality. It's funny that all three movies portray sex as something scary and then, when they have sex in the fourth movie, they have a child with really rather devastating consequences. I'm not sure what they are trying to say ... never have sex with anyone ever?"

Miley Cyrus hit up Kelly Osbourne's 27th birthday party Thursday night at the Little Door in Hollywood without beau Liam Hemsworth, but she kept his memory around her neck in the form of an "L" charm necklace. Aww!

The former Hannah Montana star Tweeted:

Just got myself an early b-day present :) how cute is this little black diamond "L" necklace! Reminds me of my boo ;)

Boo-tiful, Ms. Cyrus! See more of Miley, her new necklace and birthday girl Kelly in our gallery below.

When your daddy is David Beckham, there's no way around the girls going crazy!

While at youngest son Cruz's soccer game in LA, the Galaxy pro stood on the sidelines in sweats ... giving his boy some tips. But seems as though the women on the field couldn't control themselves after catching a glimpse of Victoria's sexy hubby.

In between coaching lil' Cruz, David posed for photographs with some of his female admirers. Lucky ladies!

Speaking of ladies, Posh and baby daughter Harper were no where in sight. Pretty soon, his little pink bundle will probably be hitting the field, too.

See more of David and Cruz on the soccer field in our gallery below.

The almost-31-year-old Ryan Gosling and the 51-year-old Sean Penn are the perfect examples of the rising Hollywood superstar and the classic, iconic film actor -- and they're starring alongside each other in the upcoming Gangster Squad.

We can't wait to see how two of our favorite stars in 1940's costumes manage to keep the mafia from infiltrating LA. Kinda like a retro Bloods and Crips!

The film also stars Josh Brolin and Emma Stone. We can't wait to see her in bright red lipstick and vampy vintage dress!
