DID MARC ANTHONY THROW A FIT OVER JENNIFER LOPEZ'S NEW MAN???!!!: File this one under Could Be True, Could Be Crap as the dubious source is "Star" magazine, but as tenious as working relationships with an ex can be, who knows, right?

According to the tab, MARC ANTHONY recently refused to work with estranged wife JENNIFER LOPEZ because he's upset about her new relationship with her 24-year-old backup dancer.

Anthony was supposed to meet J.Lo in Peru and Chile to host the auditions for their new Latin reality show :Q'Viva: The Chosen", but  cancelled his trip after a "tense conference call" with Lopez. "Inevitably, their discussion boiled down to her new boyfriend," claims the tab's source. "And Marc made the decision not to work with Jennifer last week as a result."

On a related note ... the reason the couple hasn't officially filed for divorce is because they're still negotiating the terms. According to Radar Online, "Marc and Jennifer have homes, businesses, and are minority owners of the Miami Dolphins football team. It's complicated, and it could be at least several more months before final terms of the settlement are agreed upon." When they do formally file, word is it will be in California because it's a no fault state.

ASHTON AND DEMI'S AWKWARD ENCOUNTER: Horror of all horrors!!! ASHTON KUTCHER and DEMI MOORE bumped into each other at an LA restaurant last Thursday, according to "Us Weekly".

Moore, witnesses claim, was dining at a private club with a male friend when she noticed her ex on the opposite side of the patio. According to their source,"She approached the table, he gave her a hug, and they spoke for a few minutes." Although the source claims the chat seemed "polite," the whole scene was described as "very awkward."

Sadly, no one thought to take camera phone video or at the very least snap a pic or two of their public encounter. What good is technology, people, if you're not going to use it for our amusement???!!!

UPDATE - ALEC BALDWIN "RUDE" TO AMERICAN AIRLINES CREW: American Airlines is giving its side of the ALEC BALDWIN fiasco. As we told you yesterday, the "30 Rock" star went on a Twitter rant Tuesday, fuming that a "flight attendant on American reamed me out for playing Words With Friends while we sat at the gate, not moving", and then eventually kicked him off the flight.

Now the company has issued a statement saying that Alec  was "extremely rude to the crew, calling them inappropriate names and using offensive language. Given the facts above, the passenger was removed from the flight and denied boarding."

In a letter published on Huffington Post, Alec offers an apologizing, of sorts, writing, "It was never my intention to inconvenience anyone with my 'issue' with a certain flight attendant" -- who, he claims, singled him out to make an example of him. He then goes on to trash the airline industry, saying they used 9/11 "as an excuse to make the air travel experience as inelegant as possible."

ROMANCE REPORT: We don't know how he does it, but SNL star JASON SUDEIKIS has bagged himself another hottie. Fresh off a six-month romance with Mad Men's JANUARY JONES, Sudeikis is now reportedly dating OLIVIA WILDE.

Olivia herself is coming off a string of alleged romances with some prime man-meat including Bradley Cooper, Ryan Gosling and Ryan Reynolds since her divorce from Tao Ruspoli in October.

“Us Weekly” is reporting that Jason and Olivia were spotted together at the after party for the NBC show's December 4th episode. "They walked in holding hands," says a source. Another claims that Wilde's been spotted at the SNL studios on a semi-regular basis and that "they've gone out to dinner after rehearsals."

Meanwhile … Jason’s SNL co-worker KRISTIN WIIG is being linked to Strokes drummer Fabrizio Moretti. If his name sounds familiar it’s because Moretti previously dated DREW BARRYMORE for five years.

The “Bridesmaids” star and Fabrizio were spotted canoodling at a Black Keys party Monday night at a club in Manhattan. "They were literally on top of each other," a source tells the New York Post.
