"It's a boy! Thanks to everyone out there for all your well wishes!," the 34-year-old Simmons tweeted Saturday. "More to come. Thank God. And God Bless! Kimora + Djimon Love & Light, KLS."
The Baby Phat CEO didn't stop there. She tweeted through her labor: "It's time !! No turning back! At hospital in labor right now!!" and "Having contractions now! Ooo- wee! It's like WHOA!"
Simmons even posted a picture of herself in the hospital.
So far, there's no word on the baby boy's name. Simmons already has two daughters — Ming Lee, 9, and Aoki Lee, 6 — with Russell Simmons.
