The divorce between Jennifer Lopez and Marc Anthony may have started off amicably enough... but the former's relationship with backup dancer Casper Smart has thrown a contentious wrench into the couple's split.
Following reports that Anthony was throwing tantrums over J. Lo moving on so quickly, the latest issue of Us Weekly states that Anthony is set to cause major problems between the pair.
After initially ceding primary custody to the American Idol judge, Anthony is now "going back on his word and saying his wants joint custody," an insider tells the tabloid.
Why would Anthony use the former couple's twins in such a manner? The answer is simple, says this 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."
Overall, the divorce is "getting vicious," the magazine reports.
