Katherine Heigl looks completely gorgeous.

The expectant star took to Instagram today to show off her growing baby bump in a new maternity photo, and she looks more stunning than ever. In the beautiful snap, the 37-year-old stands next to a scenic window while wearing a white crop top and high-waist black leggings as she gazes down at her pregnant tummy.

"For all you gestating ladies out there check out Those Heavenly Days for my 'Pregnancy Favs...Thus Far' and get some tips and tricks for feeling more comfortable inside and out while growing a life!" the "Doubt" actress captioned the image, referencing her personal blog where she has been documenting her journey through motherhood. Her latest post details her pregnancy tips and tricks.

This will be the third child for Heigl and her husband Josh Kelley, but this is her first time being pregnant. The couple has two adopted daughters, Naleigh, 7, and Adelaide, 4.

We can't wait to meet their impending bundle of joy.
