Kimora Lee Simmons and boyfriend Djimon Hounsou have welcomed a baby boy.

The 34-year-old Baby Phat designer made the announcement on her Twitter page late Saturday.

“It’s a boy! Thanks to everyone out there for all your well wishes! More to come. Thank God. And God Bless! Kimora + Djimon Love & Light, KLS,” she wrote.

Before the baby’s big arrival, Kimora spent part of the day keeping fans updated on her delivery with the help of Twitter messages. She even posted a picture of herself in the hospital. “It’s time !! No turning back! At hospital in labor right now!!” Her last Twitter update before making the announcement reads: “Having contractions now! Ooo- wee! It’s like WHOA!”

Kimora has two daughters — Ming Lee, 9, and Aoki Lee, 6 — with Russell Simmons. The boy is the first child for Djimon, 45, the Oscar-nominated star of Amistad and Blood Diamond.
