If you believe the reports, the Queen of Fab's life isn't so fabulous these days.
So what gives?
A source close to the couple told the New York Daily News that the 37-year-old Life in the Fab Lane star and her 48-year-old Gladiator man got into a "big fight over money," which prompted the split.
"Djimon walked out on Kimora," said the insider, adding that the decision of KLS' ex-husband, hip-hop impresario Russell Simmons, to stop subsidizing her already-lavish lifestyle may have played a part in the matter.
Adding insult to injury, the source claimed "Kimora lives as if she's the Queen of England."
The newspaper then noted that Simmons has now put her six-bedroom, eight-bath Beverly Hills home on the market for $4.7 million—well below the $5.9 million she purchase the home for in 2007, according to the Trulia Luxe Living blog.
KLS subsequently took to Twitter to apparently quash suggestions she was in financial straits, though it's worth noting she didn't address her relationship with Hounsou specifically.
"Wow, I put 1 of several properties I own (+DON'T live in) on the market & now apparently my whole life is fallin apart?!" Simmons tweeted. "Rumors, rumors…"
Reps for the pair were unavailable or comment.
For his part, Djimon obliquely addressed the subject by retweeting the erstwhile Baby Phat purveyor's comment on the matter.
Simmons and Hounsou began dating in March 2007 and tied the knot in the summer of 2008. They have a 3-year-old son, Kenzo Lee Hounsou.
