Star of The Astronaut Wives Club Odette Annable celebrated “Bump Day”  today on Wednesday, by releasing a stunning topless, bump-revealing beach shot that heralds mothers and the human body in pregnant form.

“Our future depends on the health of moms and babies. I’m celebrating healthy pregnancies by sharing my bump #BumpDay ,” the Brothers and Sisters alum captioned the visually-stimulating photo of herself emerging from the water on a beach that she posted on Twitter.

Annable and her husband Dave Annable who starred in the Red Band Society announced that they are expecting a baby girl last month on Father’s Day.

The couple met on the set of Brothers and Sisters and have been married since 2010. This is the first child for both of them.

Marvelous photo! Brava!
