Marc Anthony Threatens To Quit Latin TV Show After Fight With Ex Jennifer Lopez

A source told Star: "Marc and J.Lo had a tense conference call when she was in Morocco. Inevitably, their discussion boiled down to her new boyfriend (Smart) and Marc made the decision not to work with Jennifer last week as a result."

Anthony waited until Lopez's private jet had taken off from Mohammed V International Airport in Casablanca -- headed to Peru -- to call Idol creator Simon Fuller to tell him that he was considering quitting for good, Star is reporting in its new issue, on newsstands now.

Fuller's XIX Entertainment is the force behind the Q'Viva which will scour Latin America for untapped talent -- singers, dancers, musicians, and performers.

Lopez was photographed in Lima, Peru, and Santiago, Chile, in the past week - filming the show without Anthony.

When he spoke to Fuller, Anthony said the reason he was not traveling to the two countries was "quite simply, J.Lo. I can't work with her, he said," an insider told Star.

As one person close to Anthony said: "It's his Latin pride. It's been severely dented."

Added the source, "Discussions are now underway to resurrect his involvement in the show. Millions of dollars are on the line and producers are desperate to soothe the tension between their two stars."

After seven years of marriage, Lopez and Anthony announced they were splitting up in July.

They are parents to three-year-old twins Max and Emme.
