Marc Anthony's ex-wife is reportedly demanding more than $100,000 a month in child support.
The Grammy winner currently pays ex Dayanara Torres $13,000 a month in child support and $3,500 in spousal support, according to the New York Post.
The newspaper reports the former Miss Universe is taking Marc to court this week to demand $112,000 a month, adjusted for the singer's earnings.
"Torres, we're told, has been telling friends that Anthony doesn't pay enough child support," the Post reports.
"She has a running joke with her friends - she asks them to ask for her money if they run into Marc," an insider said.
Marc and Dayanara were married for four years and share two sons, 12-year-old Cristian and 10-year-old Ryan. They finalised their divorce in 2004, just a week before he married ex-wife Jennifer Lopez, with whom he shares two children.
Marc's lawyer, Daniel Jaffe, says his client owes nothing.
"Marc has paid every penny, well over $13,000 a month. [He] has paid for all of the kids' schooling, band lessons, camps, and all medical and dental costs. Virtually everything," the attorney said.
Marc reportedly plans to fight Dayanara in court.
A lawyer for the former model has not commented on the claims.
