Katherine Heigl announced in June that she and her husband, singer Josh Kelley, are expecting their third child together, and now we're getting a glimpse of her adorable baby bump. The actress flashed a vibrant smile when she was spotted filming scenes for her new show Doubt in LA on Wednesday. Katherine, who is expecting a boy, looked gorgeous in a black pencil skirt and blue blouse with a matching jacket. She and Josh, who tied the knot in 2007, are already parents to their two adopted daughters, Naleigh, 7, and Adalaide, 4. Judging by the family's social media snaps, their foursome is about to get a whole lot cuter.
