A judge decided the amount the hip-hop star will be paying, based on his income versus his ex's income.
The official also ruled that he will have to pay for their health insurance, part of their extracurricular activities, and for her legal fees.
The Court Compared His Income And The Kids' Mother's
Ross has three children with his ex Briana Singleton, named Billion, Berkley, and Bliss Allah.
The former couple was already broken up and embroiled in a bitter custody dispute for their two older kids when Singleton had Bliss Allah last year.
Singleton had to sue Ross to take a paternity test, as he was allegedly not taking responsibility for his kids.
Back in court this year, they submitted their monthly incomes to the judge so he could decide on a payment arrangement.
According to TMZ, court documents state that Ross has a monthly income of $585,000, while the kids' mother only brings in $142 a month.
Singleton is an entrepreneur and started her own sportswear brand, called Fit By B. Camille.
The judge used this information to come up with a ruling.
Ross Is Paying Monthly, Plus For Some Fees & Expenses
Because his income is so much higher than Singleton's, the judge presiding over the case decided that the rapper must pay her.
Ross joins the ranks of other celebs that have to pay child support, like Marc Anthony and Charlie Sheen.
The figure that was settled on for child support is $11,000 a month.
But that's not all: he also has to pay for their health insurance and up to $3,000 per kid for any extracurricular expenses that go over $7,560.
Ross also had to cut his ex a check for $25,000 to cover her legal fees.
TMZ reports that Ross has already started making the payments to Briana.
A few years ago, Ross was in court battling his other baby mama, Tia Kemp, over child support payments.
They share a 16-year-old boy together, and then Ross has a 19-year-old daughter with another woman.
