Congratulations to Reese Witherspoon and Jim Toth, who welcomed a son, Tennessee James, this morning. Reese's rep confirmed to People, saying, "Both mom and baby are healthy and the entire family is thrilled." Since news broke that Reese was expecting her third child earlier this year, the Oscar winner celebrated her growing baby bump with her usual classic-meets-casual style. The active mom kept up her exercise routine, frequently jogging around her Brentwood neighborhood, but she didn't live in workout wear. Casual day dresses with oversize sunglasses, chic ballet flats, and stylish handbags were Reese's maternity hallmarks, but she also went glam at the Cannes Film Festival and the White House Correspondents' Dinner.
