SHE'S BITTER! MASHONDA SAYS SWIZZ BEATZ IS A DEADBEAT WHO OWES BIG MONEY!

Songbird Mashonda says ex-hubby Swizz Beatz is a deadbeat who owes her big money - just as he's about to marry singer Alicia Keys.
Mashonda Dean, whose divorce from the hip-hop star was finalized two weeks ago, is reportedly targeting Swizz Beatz in Manhattan Supreme Court for missing $334,000 in alimony and child-support payments.

The "No Panties" singbird married Swizz Beatz, whose real name is Kasseem Dean, in 2004. The couple split in 2008, with Beatz moving on to Keys, the Grammy-winning singer of "Fallin'."

The couple has a 13-year-old son, Kaseem Dean Jr.

Beatz is supposed to marry Keys this summer.
