Natalie Portman's mom-to-be glow was shining through as she stumped for Hillary Clinton at voter registration events in Philadelphia Monday. The Oscar winner was all smiles as she struck a pose and covered her growing baby bump in a blush pink, long-sleeved dress paired with black tights.

Her style was effortless as usual, with the Jackie star wearing her ombré lob straight and minimal makeup aside from a soft pink lip.

The pregnant actress was on hand to encourage Pennsylvanian women to register to vote and urge their family and friends to do the same, according to Philadelphia Magazine, which reported that Portman attended four voter registration events this afternoon.

Before Portman hit the campaign trail, she continued with her casual-chic maternity stylings over the weekend in Los Angeles, stepping out in a white collared blouse and cuffed denim shorts. To give her look an edge, she rocked a mirrored pair of shades as she braved the heat wave in the city.

This is the second child for Portman and her husband Benjamin Millepied, who are already parents to Aleph, 5.
