Us Weekly: Jennifer Lopez & Marc Anthony’s custody war is getting “vicious”

Jennifer Lopez and her facially-challenged boyfriend Casper Smart are loved up all over the world. The message is clear: J.Lo, true to form and true to her relationship history, has moved on from Marc Anthony and quickly jumped into a serious relationship… with a 24-year-old backup dancer. As you can imagine, the super-controlling Marc Anthony is NOT pleased. One of the biggest issues seems to be that Jennifer is letting Casper spend time with twins Max and Emme. Marc doesn’t like it, and he’s planning on fighting Jennifer over every little custodial issue, at least according to Us Weekly:

It’s war! After what appeared to be a fairly civilized July split following seven years of marriage, things between Jennifer Lopez and Marc Anthony are getting seriously ugly, multiple insiders tell the new Us Weekly, out now.

The catalyst? Lopez’s newfound love with Casper Smart, a 24-year-old backup dancer who’s already getting along swimmingly with Max and Emme, Lopez’s 3-year-old twins with Anthony, 43.

When the Latin crooner spotted photos of Lopez and Smart bonding with his son and daughter during a Thanksgiving vacation in Kauai, Hawaii, he “hit the roof,” one source says. “It caused a huge blowup.”

Anthony’s next move: Although he and Lopez, 42, already hammered out custody arrangements for the twins — ceding primary custody to the singer and American Idol judge — a close source tells Us he’s “going back on his word and saying his wants joint custody.”

His ultimate motive, says the source? “He wants to make Jennifer suffer because she’s having fun with someone new, and he knows this will hurt her on the deepest level.”

But Lopez, says another pal, is “ready to smash him if he tries anything…It’s getting vicious.”

This wouldn’t surprise me at all, actually. It’s all “amicable” and “look at us, we’re co-parenting!” until one of the parents gets a new partner, and then all hell breaks loose. Marc Anthony is rather douchey, that’s a given, and I believe he would make an issue out of the custody just as a way to “control” Jennifer. But! Jennifer introduced Casper to her kids WAY too soon, and I kind of feel like Marc does have the right to be upset. Also: I appreciate anything that can be done to separate Jennifer and that completely FUBAR backup dancer.
