Kimora Lee Simmons got Twitter-happy this weekend! And with good reason: she just gave birth to a baby boy!

The 34-year-old sent out this Tweet the other day: "It's time !! No turning back! At hospital in labor right now!! Love & Light, KLS."

And later came the big news, that she and actor Djimon Hounsou are parents: "It's a boy! Thanks to everyone out there for all your well wishes! More to come. Thank God. And God Bless!"

Kimora also has two children with Russell Simmons...
