Former fashion model Kimora Lee Simmons gives birth to baby boy

It's a boy for former fashion model Kimora Lee Simmons and actor Djimon Hounsou.

Simmons announced the birth Saturday on her Twitter feed. A representative for Simmons says both she and her newborn son are doing great. No further details were immediately available.

The 34-year-old Simmons has two daughters with 51-year-old hip-hop mogul Russell Simmons, whom she divorced in 2008 after seven years of marriage.

The newborn's name had not yet been publicly announced.

"Kimora and Djimon are the proud parents of a new baby boy. Both mother and child are doing great," Simmons' representative told TV's "Access Hollywood."

Simmons also has two daughters with her ex-husband.
