We already heard about them hooking up, but according to music producer Marlon David, Christina Aguilera had a threesome with Samantha Ronson! Marlon said, "Jordan was never comfortable with Xtina liking girls but he thought it would make the marriage work. Sam said she had a threesome with Xtina in Mexico last month, that's when she realized she was a 'hot piece of ass'. Sam [also] said Xtina is 'horny as a college freshman'."

Marlon, who says he's friends with Sam, revealed that Christina also gave the DJ a Skype peep show, and though all this sounds pretty uh, dirrty, we hear the real reason behind the divorce was her hookups with Benji Madden at Nicole Richie's house. What a mess! How much of this do you think is true?

Heidi Klum is truly the queen of Halloween -- every year she throws a star studded bash, and she never disappoints us with her elaborate and creative costumes.

Check back here for pictures, because it's one soiree we definitely plan on crashing!

Well, Snooki IS one of the most popular Halloween costumes this year!

A pal of Vinny Guadagnino and Ronnie Ortiz-Magro tweeted this pic of the boys, and naturally they decided to poke fun at their MTV co-stars with these hilarious Halloween costumes. Vinnie squeezed into a Snooki getup, and Ronnie rocked some serious hair to complete his best Pauly D impression.

In other Jersey Shore news, Angelina "Jolie" Pivarnick was punched in the back of the head yesterday at a Staten Island mall while shopping at Hot Topic. A large group reportedly approached the starlet and a friend and a brawl broke out. Pivarnick and her pal refused medical treatment and didn't file charges.

Olivia Wilde and Justin Timberlake were snapped on the Los Angeles set of I'm.Mortal, and JT's character appears to be helping the damsel in distress here.

The movie is set in the future where the rich can live forever and the poor are forced to negotiate their immortality, and Amanda Seyfried, Vincent Kartheiser and Cillian Murphy also star in the film. Justin's character is a lower class lad who gets his hands on a wealth of time, but the authorities are after him, and it sounds like a whole lot of drama ensues.

A sexy sailor and a smokin' hot Native American? Loves!

Last night we snapped Paris Hilton, boyfriend Cy Waits, Jayde Nicole and several other celebs attending a private Halloween party in Hollywood at V-MODA Fortress, and everyone went all out for the occasion.

Of course, Paris' parents Rick and Kathy got in on the fun too!

The use of a gay slur in the trailer for The Dilemma sparked a huge controversy earlier this month, and after receiving criticism from Anderson Cooper and GLAAD, Universal Pictures removed the slur from the trailer. However, director Ron Howard says he will not remove the line from the film itself, and it seems like that's going to cause even more chaos.

Howard chatted with the Los Angeles Times and said, “I believe in sensitivity but not censorship." Howard then explained that the scene in which Vaughn describes an electric car as “gay” was scripted, not ad libbed, and that it was intended to dramatize the fact that Vaughn’s character “is far from perfect and he does and says some outrageous things along the way.” Howard added, “I defend the right for some people to express offense at a joke as strongly as I do the right for the joke to be in a film."

GLAAD president Jarrett Barrios said, “Unfortunately, by leaving it in the movie, they are now contributing to the problem. The conversations started as a result of the community’s response to this slur will help schools, media and parents understand the impact of the word ‘gay’ being used as a pejorative. Hopefully in the future, Universal and Ron Howard will recognize the power of their words and use their films to bring people together rather than drive us apart.”

Last night a ponytailed Victoria Beckham took her three sons to a birthday party at Fogo de Chao, which is the family's favorite Brazilian restaurant. We snap David and the boys there all the time, and everyone seemed to be having a blast, especially Cruz, who seemed particularly taken with a slightly older lady friend.

But speaking of David, where was he?

Kim and Kourtney Kardashian (along with Kourt's baby daddy Scott Disick) were snapped leaving their NYC hotel yesterday evening, and they were swarmed by dozens of fans on the way out. Well, not so much Kourt and Scott, but Kim seemed a bit overwhelmed with all the attention!
