What seems like one of the longest celebrity pregnancies of the new century, Kimora Lee Simmons let her Twitter followers know that was indeed in labor.

“It’s time !! No turning back! At hospital in labor right now!!” “Having contractions now! Ooo- wee! It’s like WHOA!”

Simmons’ rep confirmed today that the Life In the Fab Lane star delivered her first son this morning with new dad actor Djimon Hounsou. The Phat Fashions president already has two adorable daughters with ex-husband Russell Simmons.

Kimora and Djimon had a commitment ceremony last summer in Benin, Africa.

No word yet on the baby’s name.

Congratulations to the both of them.
