The ink has barely dried on their final divorce decree, but the war wages on for bitter exes Swizz Beatz and Mashonda.

Alicia, look what you’ve started!

Beatz, real name Kasseem Dean, split from the “Back of the Club” singer in April 2008 after four years of marriage. She filed for divorce in February 2009 and Swizz confirmed last May that he is dating Alicia Keys, fueling rumors he began bedding the “Unthinkable” singer while still in a relationship with Mashonda.

Rumors that Mashonda has been quick to confirm.

The former couple’s divorce was finalized just two weeks ago, but in new papers filed in New York’s Manhattan Supreme Court, Mashonda claims her ex already owes her $334,000 in late alimony and child support payments for their three-year-old son, Kasseem Jr.

The New York Post writes: “In papers filed in Manhattan Supreme Court, Mashonda Dean says the man who officially became her ex-husband two weeks ago already owes her $334,000 in missed payments. ‘I so much wanted both of us to get on with our lives and maintain our respect for one another, but he now shows that his priorities and sense of responsibility are screwed up,’ R&B singer Dean said. Dean’s lawyer, Bernard Clair, called the nonpayment ‘particularly troubling’ because of reports that Beatz bought a seven-carat engagement ring for Alicia Keys earlier this year and that they’re moving into a $14.5 million duplex penthouse on Crosby Street…However, Beatz has defended himself and refuted his ex-wife’s claims…He said he’d agreed to pay Dean more than the judge required and much more than his lawyer recommended — he even had to sign court papers acknowledging that he was going against his attorney’s advice. “I gave over what the judge was recommending to give. I gave her $700,000 up front, because I thought $200,000 wasn’t enough for what she wanted to do. I still get spit in my face for it,’ he said.”
