Alanis Morissette beamed yesterday while out on a walk through LA's Brentwood neighborhood with her month-and-a-half-old son, Ever! She and her husband, Mario Treadway, welcomed the little one just last Christmas, and even posted an initial photo of their family on Alanis's Twitter page recently. Mario got in on the strolling action too by taking Ever out for some fresh air today. Pregnancy suited Alanis just as much as motherhood seems to, as she bared her bump in a bikini while on vacation in Cabo last November. She and Mario are among the many stars who are happy new parents — test your knowledge of celebrity baby names by taking LilSugar's quiz!
