Katherine Heigl Shows Off Her Baby Bump in Relaxed Separates

Looks like things are coming along nicely! Katherine Heigl's ever growing baby bump accompanied her as she took a break from filimg her new show Doubt to run some errands on a rainy Los Angeles day. The soon to be three-time mama looked cozy in a pair of leggings and a gray knit top as she grabbed a smoothie and a water from Juice Crafters. The former Grey's Anatomy star appeared to be in high spirits as she smiled for the cameras from behind her sunglasses, despite the unusually dreary weather.

This will be Heigl's third child with husband Josh Kelly, and their first biological one. The Hollywood couple has two adopted daughters, seven-year-old Nancy Leigh 'Naleigh' Mi-Eun and four-year-old Adalaide Marie Hope. Heigl and Kelly recently announced that their newest family member, who is due in January, will be a son.

January will be a great month for Heigl and her growing family as her new series Doubt is set to debut the same month.
