KIMORA LEE SIMMONS, DIJIMON HOUNSOU SPLIT

Kimora Lee Simmons and Djimon Hounsou are calling it quits. The couple of 5 1/2 a half years have "officially separated," his rep tells Us Weekly. "Though never married, they have one child together, Kenzo Lee Hounsou, who is three and a half years old."

"There have been quite a few hurtful rumors circulating. The truth is Djimon and I have been separated for some time," Simmons shared in a statement on Twitter Wednesday. "We have remained happy, loving, co-parenting friends and family. We all have much to be thankful for."

The actor and the 37-year-old fashion designer/entrepreneur first began dating in 2007, shortly after she separated from husband Russell Simmons. Although some reports state Kimora and Dijimon were never married, due to the fact she would lose her alimony.   We have to shoot down the rumors because Kimora is a multi millionaire in her own right.

But we knew something was up months ago, if you follow Kimora on twitter she stop showing pics of her husband and her kids for at least 6 months.

Simmons was wed to the Def Jam founder from 1998 until 2006; their divorce was finalized in 2009. In addition to Kenzo, Simmons is a mom to Ming, 12, and Aoki, 10, with her ex-husband.
