Pregnant Katherine Heigl Cradles Her Growing Baby Bump on the Set of 'Doubt' -- See the Cute Pics!

Katherine Heigl already has that pregnancy glow.
The 37-year-old actress was snapped on the set of her new show, Doubt, on Tuesday in Los Angeles, looking gorgeous in a blue blouse and a knee-length black skirt. Keeping her blonde hair down in soft waves, Heigl sweetly touched her baby bump as she filmed scenes for the courtroom drama.
And she was also able to give her feet a much-needed break from heels! Though she wore black pumps for the scene, Heigl changed into a comfy pair of brown slip-ons in between takes.
Heigl is currently pregnant with her and husband Josh Kelley's third child, after previously adopting their two daughters, 7-year-old Naleigh Moon and 4-year-old daughter Adelaide. The couple is expecting a baby boy, due in January.
"We've known for a while that we wanted to add to our family and frankly didn’t really care how we chose to do that," the former Grey's Anatomy star revealed in a blog post last month. "We were considering adoption again, fostering, or pregnancy if possible. Seeing as I have never been pregnant and as my OB/GYN reminded me last year, I'm of advanced maternal age, I wasn't sure pregnancy was even in the cards for us. Turns out it was very much in the cards!"
