Kimora Lee Simmons and Djimon Hounsou Split

Pair announced their separation this week

It's not shaping up to be the happiest of Thanksgivings for Kimora Lee Simmons and Djimon Hounsou.

The stylish couple has announced that they are splitting up, E! News has confirmed.

"Djimon Hounsou and Kimora Lee Simmons have officially separated after 5½ years," the actor's rep said in a statement to E! News. "Though never married, they have one child together, Kenzo Lee Hounsou, who is 3½ years old."

The Queen of Fab and her Oscar-nominated actor-model beau began dating in March 2007. Along with their child together, Simmons also has two daughters—Ming Lee, 12, and Aoki Lee, 10—from her marriage to rap/media tycoon Russell Simmons.

Back in June, the duo shot down split rumors as well.

Simmons addressed the split on Twitter: "There have been quite a few hurtful rumors circulating. The truth is Djimon+I have been separated for some time. We have remained happy, loving, co-parenting friends+family. We all have much to be thankful for."

She added in response to a fan: "We do the best we can."
