JERRY SEINFELD
Seinfeld, 51 – once known as a confirmed bachelor – says of fatherhood, "Oh, I love it." And the funnyman – whose 6-month-old son Shepherd joined daughter Sascha, 6, and Julian, 3 (with wife Jessica Sklar, 35) – has found an appreciative audience. "The best laugh in the world is little kids," Seinfeld said on theTodayshow.
