Katherine Heigl is making her first red carpet appearance since announcing her pregnancy, and the 37-year-old definitely has that mom-to-be glow.

The Doubt actress brought her burgeoning baby bump to the 2016 Television Critics Association Summer Tour Party on Wednesday, stunning in a white form-fitting sheath while walking the red carpet alongside her husband Josh Kelley.

The Grey’s Anatomy alum, who shared the news of her first pregnancy on her website in June, flaunted a sliver of cleavage in the cutout number, which featured a demure knee-length hemline, flattering elbow-length sleeves, and a fitted silhouette. She paired the cream ensemble with leg-lengthening pointy-toed nude stilettos, delicate gold jewelry, and a statement floral print clutch.

The expectant mother, who kept one hand cradling her bump for the event, showed off her lit-from-within complexion by sweeping her blonde hair away from her face in an airy old Hollywood-inspired updo and playing up her features with a purple-toned smoky eye and peach lip.
