Let the battle of the exes begin!

This time Marc Anthony is putting his foot down when it comes to JLO’s new man driving Max and Emme around--- the twins he shares with ex-wife Jennifer Lopez.

RadarOnline.com reports that the Salsa crooner told Lopez that her boy toy Casper Smart is not allowed to drive the kiddies anywhere because of his illegal street racing fiasco and criminal record that looms.

[Mark Anthony] "went ballistic when he found out about Casper's criminal record,” a source told RadarOnline.com

“He explicitly told Jen that Casper wasn't allowed to drive their children anywhere.”

The undisclosed source added that “Marc hates the fact that Casper is spending time with Max and Emme” and that “Marc is extremely jealous.”

“[He] doesn't think Jen is using good judgment when it comes to Casper."

The Puerto Rican crooner also told Lopez that if she dismisses his request “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 source added.

Smart, 24, whose given name is Beau Paul Smart, was caught driving without a valid license back in 2004, 2006 and 2007, according to an E! report.

Recently, Smart was charged with participating in an illegal highway street race. He is currently out on a $26,000 bail.

Smart faces court time Jan. 5, 2012 and must complete 10 days of community service since he “pleaded no contest” to the illegal street racing charge,” the NY Daily News reports.
