Puttin' the baby in Baby Phat! Kimora Lee Simmons and her husband, Tim Leissner, have welcomed their first child together, a rep for the former model confirms to Us Weekly

Simmons, 39, gave birth to a baby boy, son Wolfe Lee Leissner, her rep tells Us. No further information was immediately available.

Wolfe is Simmons' fourth child. The former Baby Phat CEO also shares son Kenzo, 5, with actor Djimon Hounsou, and has two daughters, Ming, 15, and Aoki, 12, from her marriage to ex Russell Simmons. (The two finalized their divorce in 2009, but split after eight years of marriage in 2006.) 

Us confirmed the designer's pregnancy back in October, seven months after news broke that she'd secretly wed Leissner. "Tim has been family for a while now," Def Jam co-founder Russell tweeted at the time.
