Congratulations to fashion designer Rebecca Minkoff, who gave birth to her first child on Sunday. Minkoff and her husband, Gavin Bellour, are the proud parents of a 6-pound, 14-ounce baby boy. Minkoff posted a picture on Twitter of her actor husband and the baby, with the words, “The cutest family in the world.” A happy reason for Minkoff to miss the Vogue/CFDA launch of her new sunglasses collection tonight at the Sunglass Hut flagship store on Fifth Avenue.
