Kimora Lee Simmons is pregnant with a baby boy. Her daughter Ming Lee Simmons broke the news on her Instagram over the weekend. "IT'S A BOY," so she captioned a photo of her and some girlfriends taken during her celebrity mother's baby shower. The background of the pic showed blue balloons that further confirmed the exciting news.

Ming Lee also posted another picture of herself kissing her mother Kimora's cheek. "@officialkimora #itsaboy #babyleissner," so she captioned the shot. Also attending the baby shower were Kimora's former husband Russell Simmons and fellow actress Garcelle Beauvais. The threesome posed for a photo alongside Kimora's husband Tim Leissner.
