Just when things started seeming (almost) friendly between exes Jennifer Lopez and Marc Anthony, Jennifer's new beau Casper Smart is driving them apart. According to RadarOnline.com, the American Idol judge's ex-husband is livid that Smart, who has been arrested for drag racing and had warrants out for his arrest, could be driving his twins Max and Emme around.
Anthony "went ballistic when he found out about Casper's criminal record. He explicitly told Jen that Casper wasn't allowed to drive their children anywhere. Marc hates the fact that Casper is spending time with Max and Emme. Marc is extremely jealous, and doesn't think Jen is using good judgement when it comes to Casper," a source tells Radar.
"This wasn't a threat that Marc gave Jen. He will go straight to family court if he needs to get a judge involved to make sure Casper doesn't get behind the wheel with his kids in the car," the insider says.
The tension between the former couple has even bleeded into their once-civil working relationship (they both have clothing lines with Kohl's and jointly produce and star in reality show Q'Viva: The Chosen). "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," the insider told Star Magazine.
