The former model and designer has been married to her husband Tim Leissner, 45, for a little over a year. 

This is the first child she has with Leissner, who is a financier for Goldman Sachs.

“We are filled with joy, adoration and gratitude as we celebrate the birth of our son,' the couple told PEOPLE.

Baby Wolfe is Kimora's fourth child, as she has two daughters with former husband Russell Simmons and one son with former partner Djimon Hounsou.

Her daughters, Ming, 15, and Aoki, 12, share the same last name with both their mom and their dad.

Kenzo, who is five, has his father's last name of Hounsou. And baby Wolf will also take his father's last name of Leissner.

The TV personality posted a photo of her and Leissner four weeks ago.

Dressed in black formal evening attire for a Goldman Sachs event, Kimora wrote the hashtag   #BabySTILLonBoard as her husband wrapped one arm around her waist and proudly rested the other on her stomach.

PEOPLE reports that the happy parents are 'ecstatic' while 'resting and doing well after the delivery.'
