Their new baby, Oliver, is the couple's first child together. Puck, 56, and Assefa, a 35-year-old fashion designer, plan to tie the knot next year.
Puck has two other sons from his previous marriage to restaurateur and designer Barbara Lazaroff.
A culinary superstar, Puck has cooked up delectable creations for such high-profile events as Tori Spelling's wedding, the Governors Ball following last year's Oscars and a birthday bash for Julia Roberts.
