Scorching hot duo Kimora Lee Simmons and Djimon Hounsou are about to become a trio.

The couple are expecting their first child together, sources close to the Baby Phat designer confirm to E! News.

Simmons has yet to publicly announce the pregnancy, but her New York staff was informed last week, an insider says.

The 33-year-old star of Style Network's Kimora: Life in the Fab Lane has two children—Ming Lee, 8, and Aoki Lee, 6—from her near decade-long marriage to hip-hop impresario Russell Simmons. That union dissolved in March 2006, but the divorce wasn't finalized until March 2008. They remain friends and business partners.

She and the 44-year-old two-time Oscar nominee, both former models, met in February 2007.
