A feud brewing between Hollywood’s Highest-Paid Actress and Jennifer Aniston’s ex is threatening to disrupt filming on the new film FOUR CHRISTMASES. Reese Witherspoon and Vince Vaughn co-star in the romantic comedy, but according to reports the shoot is being hampered by the pair’s arguments over Vince’s “laid back attitude toward work.”

A mole tells the New York Daily News: “Vince rolls onto set in the morning looking like he just came in from a night out, while Reese will arrive early looking camera-ready. “Then Reese tries to force Vince into blocking out each scene and running through their lines as Vince tries to convince her that he’s an ad-libber and wants to play around and see where the scene goes. “She’s a one-take perfectionist and Vince likes to try it a few different ways. Sometimes Vince will be standing behind her and he has this look on his face that he just wants to kill her!”

According to celebrity sighting snitchs spied Paris Hilton and Vince Vaughn getting flirty at the World Poker Tournament Invitational at the Commerce Casino in California. Careful Vince, she burns.

Snitching sources tell Fame Magazine that former flames Jennifer Aniston and Vince Vaughn have decided to remain friends…..with benefits.

“When Vince saw her again at dinner in January, that spark was still there. “They both admitted it afterwards. “But they’re realistic about their chances of committing properly so they’ve decided to just be friends with benefits.” It turns out there are no set rules but Jen sees it as spending time together with “no strings attached”.

The tattle continued: “It just makes sense. They love spending time together, they’re great friends and they trust each other. “So why not have some fun until something serious turns up?”

Us Weekly Reports:

After nearly 60 days apart, Jennifer Aniston has arrived to see Vince Vaughn. On the night of October 27, Us has learned that the actors shared the penthouse suite at a London hotel, where the pair ordered room service (steak, veal and red wine). It was the first time the on-off-on again couple had seen each other since their break up (a split that an Aniston friend later downgraded to a “break”). The next day, on Saturday, October 28, the couple took in a matinee performance of the musical Wicked, then returned to the hotel.

Darn,
I was really hoping that Jen was a free agent. I recently hired a private investigator to track down her cell phone number so I could give her a call…
