Gwen Stefani by Jean Baptiste Lacroix/ Gwen Stefani by Jean Baptiste Lacroix/

Pop diva Gwen Stefani is pregnant with child No. 2 with husband Gavin Rossdale. As if their 20-month-old Kingston wasn't already the coolest toddler in town, they'll now have an opp to repeat the performance with this sophomore effort.... Dixie Chick Martie Maguire's also with child, which will be her third with husband Gareth Maguire. The music star, 38, had twin girls in 2004.... And even though it was only yesterday that Fred Savage was a nerdy teen on TV, he is somehow about to become the dad of a second child for him and his wife, Jennifer Stone. We'll check back in 2018 to see how those real-life wonder years are treating him with two tweens in the house. - Anna Dimond
