Katherine Heigl Shows Off Her Baby Bump While Filming 'Doubt'

Katherine Heigl holds onto her baby bump while filming a scene for her upcoming TV series Doubt on Tuesday afternoon (August 2) in Downtown Los Angeles.

The 37-year-old pregnant actress didn’t try to conceal her growing bump while filming late last month either, so it seems like it could be a part of the story line!

A few days earlier, Katherine took to her Instagram to share a super sweet photo of her daughters, four-year-old Adelaide, and seven-year-old Naleigh.

“Way to my girls hearts! Family ice cream night!” she captioned the cute photo.
