Now, the expectant mother is dressing her bump in an elegant business ensemble straight from the set of her new CBS drama, Doubt, and we are huge fans of the chic look. The blonde actress stepped out in downtown Los Angeles on Tuesday for filming, and she is definitely giving Scandal's Olivia Pope some fierce competition with her office-ready look. The 37-year-old highlighted her growing baby bump by tucking a crisp dark blue button-up shirt into a high-waist pencil skirt. She topped off the outfit with a form-fitting navy blue blazer, which she cinched with a matching belt, accessorizing with leg-lengthening black pumps and a work-ready black leather bag. The mom-of-two, soon to be three, looked more than ready for her close-up with a meticulously styled blonde lob and red lips.
