Marc Anthony

"Extra's" Terri Seymour caught up with her good friend Simon Cowell to talk about the chemistry on the "X Factor" set -- and about the recent Jennifer Lopez and Marc Anthony divorce news.

"I didn't see it coming," Cowell said about the couple's split. "They always seemed to get on. They would bicker, but everyone bickers."

Speaking of bickering, how are "X Factor" judges Paula Abdul and Nicole Scherzinger getting along? "No rivalry whatsoever," declared Cowell, adding, "You know we've got names for them now -- Sylvester the cat, and Tom from Tom and Jerry. Sylvester's Nicole and Tom is Paula."

New details on the demise of Jennifer Lopez and Marc Anthony's marriage continue to surface, with the latest report saying the singer/actress wanted to leave two years ago when she found out Anthony had an affair with a flight attendant, reports Us Weekly.

A source told the mag that Anthony, 42, hooked up with a flight attendant he met aboard a private plane in 2009, saying, "Marc and Jennifer almost split up over it."

Ending their seven-year marriage was a decision that came "after months of non-stop arguing," a source close to Jennifer Lopez and Marc Anthony revealed to People. The bickering was sparked by issues on a movie set, jealousy on the "American Idol" stage, and Lopez's suspicion of Marc's infidelity.

An insider close to Anthony says the cheating accusations are not true, and believes the 42-year-old singer always supported his wife's career. "They started to see things differently," the source said, adding, "Though they love, admire and respect each other very much, they just needed to be apart."

When the couple announced their separation on Friday, they also revealed they had "come to an amicable conclusion on all matters," prompting many to believe their decision was reached some time ago.

Meanwhile, J.Lo has escaped the media madness surrounding her breakup and is currently in the Ukraine, where she will perform at a billionaire's wedding for a million-dollar paycheck.

They're worth $200 million combined, but did Jennifer Lopez and Marc Anthony have a prenuptial agreement when they married in 2004? Word is, there was no prenup, but there is a post-nup, and the details are top secret.

Jennifer, the face of Gucci, Gillette and L'Oreal, is worth a reported $150 million, and is considered a one-woman empire with her clothing, perfume, and production companies. Marc is worth $40 million, earning upwards of 10 million a year and selling 11 million records.

They shared seven years of marriage, two kids, and even a reality show. What went wrong between Jennifer Lopez and Marc Anthony? "Extra" is breaking down the clues behind their split -- and how much is at stake for the power couple -- reportedly worth almost $200 million.

The first clues point to their time spent apart; the couple had not been seen together in public since early June. Last month, J.Lo went to promote her "Love?" album in Europe without Anthony by her side.

Despite Jennifer Lopez and Marc Anthony announcing their shocking separation on Friday, the two still plan on working together on their Latin reality show, "Q'Viva!"

A statement from XIX Entertainment's rep confirmed the superstars will move forward with their show.
